  • pabbeel Pieter Abbeel (@pabbeel) reported

    @SlackHQ -- once I click on the "reply to a thread" icon it'd be great to just be able to type into that thread; instead it still requires clicking on the text area in the thread to be able to start typing a reply. Seems my use case should be most people's? Can you fix?

  • BordenBathory Lizzard B. Vicious, M.A. (@BordenBathory) reported

    Hey @SlackHQ my app keeps closing out while trying to respond or send media files. Was told to clear the cache, still happening then get an error saying to update the app. But there's no update for it rn on Android What's up?

  • qixotl Chris Payne @qixotl@mastodon.gamedev.place (@qixotl) reported

    @SlackHQ Aha I was able to fix it by closing Slack, killing all the background threads and restarting. Would be nice if exiting Slack actually exited.

  • DomKent Dominic Kent (@DomKent) reported

    @LetsDoVideo @SlackHQ 12m is definitely right for 2020 but I haven't heard/seen any advance on that. And I'm checking almost every day for this kind of stuff! I can't even find anything connected that would suggest it's done a data dip and made an error.

  • RachelsWillis Rachel Willis (@RachelsWillis) reported

    @1Password how do I get my 1passwords to move out of my #general feed in @SlackHQ? My team is covered in these notifications. I need them to go to the 1Password app that is listed! HELP!!!

  • 1dan Dan Berlyoung 🇺🇦 (@1dan) reported

    Is the @SlackHQ @Twitter app not working for everyone else too? #yetAnotherTwitterServiceShutdown #yetAnotherReasonToUseMastodon #Mastodon

  • vure89 Vure (@vure89) reported

    @SlackHQ I only use your desktop client and have used your website a handful of times to onboard new starters through the workspace admin page. Why on earth is your service worker cache in Chrome's Application Support path chewing up 550mb of disk space?

  • alexbcnd Alex Barreto (@alexbcnd) reported

    @SlackHQ Tried refreshing, and no change, still have the same issue. The other workspace had to add me as a guest which gave me access to the channel but now I have to switch workspaces to access the channel

  • StreamOfRon #RONDACTED 🐀 (@StreamOfRon) reported

    @SlackHQ "Is slack down for anyone else?"

  • mestachs Stéphan Mestach (@mestachs) reported

    @SlackHQ Well I don't have them anymore but was mainly usergroups, broken links in the "where" and problems with date formats (specifying am/pm) Sometimes I wish it a UI instead of plain text ;)

  • Christophepas Christophe Pasquier 🇺🇦 (@Christophepas) reported

    @Shahor @SlackHQ I guess they try to fix the issue in large orgs where 100 people are in the same thread, but agree, feels like they're fixing the design issue with another issue.

  • Unacceptable22 Robert Jackson (@Unacceptable22) reported

    @MicrosoftTeams Stop enforcing CRLF in code blocks on teams. Not everyone uses @Windows for work. It's so annoying to have to edit every single bit of terminal output when I want to share something with a colleague. @SlackHQ doesn't have this issue.

  • 1kush1 kush (@1kush1) reported

    @johnnyrodgersis @SlackHQ What happens in case slack is down.. what is your backup communication channel?

  • sol_orwell Sol Orwell (@sol_orwell) reported

    @SlackHQ Minor but infuriating bug - if you click on the "reply to thread" button, it puts your keyboard cursor in the main chat and not in the thread. It did not do this previously. Please fix as I run into this a dozen times a day right now.

  • mackemode Tyler Macke (@mackemode) reported

    @SlackHQ Previously, when I clicked the thread icon above a message, it would move my cursor to the thread tab on the right side. Now, it does not do that... and I keep sending messages in the channel 🤦 Is this a known issue and/or any plans to fix?

  • ashish_shendure Ashish Shendure (he/him) (@ashish_shendure) reported

    IMO Slack for iOS is easily one of the worst performing apps when it comes to syncing notifications, especially when you are traveling internationally. @SlackHQ will get folks in trouble some day 😬

  • kberwin K Erwin (@kberwin) reported

    @SlackHQ @themoah Is there a way to update the login screen so that logging in with email/password is the default for our org? We have 2FA enabled for all users. Getting an email code and then entering another code is kind of ridic. Also, email is sometimes inaccessible.

  • SF_Truth_Seeker Fred (@SF_Truth_Seeker) reported

    @gwestr @SlackHQ To be fair, vast majority of large mid sized enterprises never went down the full slack rabbit hole. Just seems that way because of the bubble we live in.

  • antculver .anthony (@antculver) reported

    @jmugizi I seriously don’t understand why my preferences don’t persist across Slack spaces when they’re all tied to the same login. Feature request alert @SlackHQ lol

  • serg81033 Serg (@serg81033) reported

    @SlackHQ Very disappointed with the Slack app. This morning my section was deleted without warning. All my data is gone! Terrible service! Do not store your data there!

  • CollinMickels Collin Mickels (@CollinMickels) reported

    @SlackHQ huddles have been weird / broken for the past 24 hours or so

  • enobacon 😀🚲 @enobacon@urbanists.social (@enobacon) reported

    so today in @SlackHQ I took a small square screenshot of the clown face emoji, turned it upside down, and added it as an :upside-down-clown: emoji, but it renders shrunken. Why is this not easier?

  • jamonholmgren Jamon (@jamonholmgren) reported

    @Gerka I'd love it if @slackhq would allow designating certain channels as "topic+thread" channels, and in order to post in the main channel you'd have to click a button labeled "New topic". Every topic would have a "reply in thread" button under it by default. That would fix 90% of it.

  • ohryan Ryan (@ohryan) reported

    Anyone else have the problem where @SlackHQ threads don't get updated for quite some time after logging in for the first time everyday. It's seems to take anywhere from 15 to 60 minutes for me.

  • emilyh0u emily (@emilyh0u) reported

    @SlackHQ your Okta integration doesn’t work help

  • jklida Joe Klida (@jklida) reported

    @SlackHQ please stop forcing the move to huddles until you fix the lack of a ringer. Every time I get the "Support for Slack calls ends in March" notice, I consider moving to Teams. Please don't make me do it.

  • camilosantana camilosantana (@camilosantana) reported

    @SlackHQ @mary_rose_fox is there a github issue? is this being tracked anywhere? should i be looking at alternatives other than slack?

  • MFAminGP Farhan Amin (@MFAminGP) reported

    Why @SlackHQ has become such a terrible app on Mac can anyone share their thoughts?

  • tarintowers Ariel Phenomena (@tarintowers) reported

    @SlackHQ @catovitch Hey Slack how’s that bug fix coming

  • danituits Dani 🫀 (@danituits) reported

    @dwiskus @SlackHQ They’re more powerful than replies, IMO. I’d like to have the option to be notified or not (per channel) about replies made in threads I haven’t participated in yet, but that’s it. I think they help keep the channel tidy. What does annoy you?
