Slack Issues Reports

Latest outage, problems and issue reports in social media:

  • margreyn mountain margarine (@margreyn) reported

    @SlackHQ One of my coworkers uses a screen reader on iPhone and the new Slack update has made it so they can’t see time stamps, names, statuses, or the status emoji next to the name. Is this a known issue or an easy fix? (iOS 14.1, Slack 20.11.20)

  • Derander Andrew Moreland (@Derander) reported

    I remember having blood pressure issues because 2015 hipchat would fail to deliver > 50% of messages. Starting to have daily delivery failure with @SlackHQ as of late. Looking forward to the next cycle.

  • BradfordBenn Bradford Benn (@BradfordBenn) reported

    @stiner @SlackHQ I agree. I do not fault Slack, get what you negotiate not what you deserve. I think the “play” is to keep companies entirely in Salesforce. No Zendesk/Chatbot for customer service; use Slack. Just slowly building an eco system.

  • dhrupadkarwa Dhru (@dhrupadkarwa) reported

    Of course, there's a huge issue of privacy but I wonder if this could be tackled (partly) by anonymising data... CC: @SlackHQ @stewart

  • sv02 sv02 ❄️🌎🗽📎🏳️‍🌈 (@sv02) reported

    @SlackHQ It doesn’t seem to be noted in the shortcuts help center page, but a colleague told me that command + shift U should do the trick... confirming it does! Still confusing as all other apps use command-k for the same action but at least something exists !

  • nickjsheriff Nick (@nickjsheriff) reported

    @Jason @SlackHQ Here are the facts $87 billion invested annually and over $50 billion will be spent on mobile app installs ads, and 98% of those users will churn in 3 days, some of those co will keep their valuation, pivot and not have a down round but statically most will die within 2yrs 💀

  • DaveEllisDev Dave Ellis (@DaveEllisDev) reported

    @SlackHQ Your latest iOS app has broken slash commands. The slash command is being included in the parameters.text now. Desktop and Android don’t do this.

  • SteveOfMaine Steve Sawczyn (@SteveOfMaine) reported

    Hey @SlackHQ There seems to be an accessibility issue in the latest iOS version of Slack preventing VoiceOver users from hearing user names. This makes the app nearly impossible for me to use as I can’t tell who is saying what any more.

  • Benjamin_Miller Ben Miller (@Benjamin_Miller) reported

    Salesforce is down for some users this morning and oh my god is that low hanging fruit for a @SlackHQ pun

  • LeonieWatson Léonie (@LeonieWatson) reported

    @SlackHQ I can't take a screenshot, but I don't think it would help - the problem happens in every channel of every workspace I use, so it's the application that is the important bit I think.

  • PatelPeace Peace Patel (@PatelPeace) reported

    annndddd @SlackHQ goes down in the drain with it's acquisition by @salesforce. Now what the hell am I gonna use? Teams? Oh god no.

  • iamsiddshah Siddharth Shah (@iamsiddshah) reported

    VCs: stop bragging about something you haven't done You didn't help create @SlackHQ You didn't grow @amazon Give credit where it's due Not everything is about VCs ffs 2/2

  • zohocares ZohoCares (@zohocares) reported

    @sp00x @zohocliq @SlackHQ Apologies Rune, we faced an intermittent issue while accessing Cliq from the EU region. However, connections are restored and we're closely monitoring it to avoid any further disturbances. -Divya.

  • adrianvja Adrian von Jagow (@adrianvja) reported

    @SlackHQ If a members is on "inactive" billing status, do they stop receiving notifications until they log into Slack again? If yes, is there any way to change this? Thanks for your help!

  • andre347_ Andre de Vries (@andre347_) reported

    @salesforce could you please make it a huge priority to fix @SlackHQ way of working with the different workspaces and having separate usernames + password for each of them. It's completely unintuitive.

  • zeydou Allahoum zeyd (@zeydou) reported

    @SlackHQ help needed please. On a workflow, using google sheet ones. There is "add" "update" "remove" and "select". How does select work ? I was under the impression it would bring the data to slack but... nope

  • BoralMitesh Mitesh Boral (@BoralMitesh) reported

    Acquisition of @SlackHQ by @salesforce can actually help revive the entire product of SLACK which can optimize its value to its actual potential. It can rebuild Slack with the lean product vision which it was missing.

  • vinnytroia Vinny Troia (@vinnytroia) reported

    Who knew that a watered down clone of IRC would one day sell for 27Billion. Congrats @SlackHQ !

  • adamrenklint Adam Renklint (@adamrenklint) reported

    @SlackHQ has shipped a terrible bug on iOS that randomly marks all conversations as read. Had to delete the app to not open by habit and lose track of valuable conversations. Pro tip: invest enough into QA to never break core functionality.

  • harpaa01 Aaron Harpole (@harpaa01) reported

    @tweetbot 🤞that y’all can fix this, if for no other reason than to allow me to publicly shame @SlackHQ into fixing the same issue.

  • mooreds Dan Moore (@mooreds) reported

    @SlackHQ Do you happen to have a pointer to how to fix Edge lying around?

  • MarcoInEnglish Marco Zehe (@MarcoInEnglish) reported

    @SteveOfMaine @SlackHQ Confirmed, but only in a single thread. Channel main views are fine, but VoiceOver support for single thread views is largely broken.

  • timdang Tim Dang 😷 (@timdang) reported

    @GIPHY images never show up on @SlackHQ for iPad. Will the Salesforce acquisition fix that?

  • PushingForty 😷🤝🚫 (@PushingForty) reported

    @SlackHQ on your iOS app I am having an issue where it is automatically marking channels as read. I can actually see in my channel list a channel pop up with unreads and then it just marks as read and goes away

  • m_urrecha Miguel Urrecha (@m_urrecha) reported

    Good ideas do matter and make a difference. Same guy @stewart failed miserably with an idea called Glitch, and had some 27.7bn success with another idea called @SlackHQ This also shows relevance of great teams.

  • Gilaniath Izzy (@Gilaniath) reported

    @SlackHQ Someone in my organisation running iOS 14.1 and Slack 20.11.20 while using a screenreader is having a pretty big issue: usernames are not being read out at all, not even when selecting individual messages. Any idea what’s up?

  • thejohnharman John Harman (@thejohnharman) reported

    @jackwatson05 @SlackHQ Is it the Creative Residency Fund one? I know I get similar things every so often due to being a multichannel guest in that one and I have to re-login via the browser to authorize it.

  • JoshuaNozzi Joshua Nozzi (@JoshuaNozzi) reported

    @JStheoriginal @SlackHQ Apparently turning off hardware rendering somewhere in the bowels of its settings is what they recommend, but people say that slows the editor way down. As a coworker said, the recommended fix is to break it some other way.

  • JStheoriginal Justin Stanley 👨‍💻 (@JStheoriginal) reported

    Is there any way to fix the @SlackHQ app constantly flickering on macOS? Or is it just me?

  • AllharlowsEve Harlow. 🌙🕸 (@AllharlowsEve) reported

    @SlackHQ I updated the iPhone app and now, using voiceover, I can't see usernames, even if I tap on messages. This is a major issue, obviously. Send help 😭
