Latest outage, problems and issue reports in social media:

  • DarkainMX Vincent Milum Jr #MakeGoodJumps (@DarkainMX) reported

    @SlackHQ PLEASE read the post. The problem is that in fact, *NO*, you're actively blocking BROWSER access from browsers like FreeBSD. We have to use a user agent spoofer in order to get around this. PLEASE stop blocking user agents from browser access!

  • FreshworksInc Freshworks Inc (@FreshworksInc) reported

    🌐 Help agents stay connected while remote. Integrations with communication platforms like @SlackHQ or @MicrosoftTeams help agents save up to 120 clicks every day. #FutureOfWork

  • patwoodsdesign Pat Woods (@patwoodsdesign) reported

    @SlackHQ I'm back on overnights and this schedule thing is still an issue, a year later.

  • kiran_thakare Kiran Thakare (@kiran_thakare) reported

    @SlackHQ Hi, I am struggling to use the application on Windows 11, is there any compatibility issue for the software with the new update of Windows?

  • LifesOccult Daft Coins (@LifesOccult) reported

    Hiding your @SlackHQ #Huddle status isn't the problem @nicolemichele5. A lack of trust in Mashable's culture is the real issue you want to address.

  • JackTheRipla Jakob (Jack/XDjackieXD) (@JackTheRipla) reported

    @SlackHQ Do you by any chance know if some of your servers could have problems since two or so days? I'm currently in 3 slack workspaces of which two work fine but one takes *ages* (>10minutes) to send a single message... Consistent across devices and internet connections.

  • ndimichino Nick D (@ndimichino) reported

    @SlackHQ I use both but this issue isn't on desktop

  • Pseudomanifold Bastian Rieck (@Pseudomanifold) reported

    The Linux $Slack client version 4.23.0-1 appears to have a regression that prevents users from joining new workspaces. Had to downgrade to 4.21.1-1 to 'solve' this issue. Anyone else having this issue? (@SlackHQ, thought you might want to know)

  • timotab Timothy Hunt (@timotab) reported

    @SlackHQ uploading images seems broken from iPhone app right now. Text posts ok, but no image in that post. No error, just posts without the image

  • Brunty Matt Brunt (@Brunty) reported

    @SlackHQ I've restarted my PC. I've cleared Slack caches and restarted. I've chosen other audio devices. I've re-installed Slack. Same problem. Zoom works fine, so it's not my audio device(s)!

  • critters_r_us Charlie Ritter (@critters_r_us) reported

    My current curse is trying to use @SlackHQ’s colon shortcut for emojis on all platforms and it not working :bigsad:

  • rthangam123 Ramesh Thangamani (@rthangam123) reported

    @SlackHQ yes any help doc ?

  • wouldeye125 Andrew McCartney☆ (@wouldeye125) reported

    @SlackHQ Hey your tab+return is broken again; it's tab+tab+tab+return again. just FYI I know you guys aren't doing that on purpose.

  • cambaughn Cameron Baughn (@cambaughn) reported

    Turns out, the error was on @SlackHQ’s end. They have a bug that is resulting in the app home not rendering. Now, I’ve been waiting for them to fix it for two weeks while I twiddle my thumbs. 🙃 (Okay, I’m working on other things in the meantime, but still...)

  • s4m_bloch Samuel David (@s4m_bloch) reported

    @SlackHQ Sometimes when I huddle and someone's late I want to listen to the music and slack someone else, but when I do the music stops, can we change that? #help #ideas

  • CaerelsJan Jan Caerels (@CaerelsJan) reported

    @SlackHQ Every time I get a Slack call, I click accept, but there's an unneccesary notification in the DM of that person, that he/she started a call. Kinda annoying since I am in that call ATM :-) Can you fix that?

  • damnitness Nessa B. (@damnitness) reported

    @SlackHQ Can you give me some sort of service number so I know you will follow this

  • JackTheRipla Jakob (Jack/XDjackieXD) (@JackTheRipla) reported

    @SlackHQ nevermind. The problem reappeared. Now on all workspaces I'm using...

  • kriswuollett Kristopher Wuollett (@kriswuollett) reported

    @SlackHQ “If there are overlapping events on your calendar, the Google Calendar app will not update your status.” seems problematic too since I’ve often seen calendar being double booked busy on purpose (to hold a conference room). So that’s a problem if status auto away is turned off.

  • skbakken Sam Bakken ***Black Lives Matter*** (@skbakken) reported

    Hi @Zoom & @Microsoft (Snipping Tool specifically) & (maybe) @SlackHQ -- there is a bug where I can't leave zoom meetings when during a day I use parts of each of you. I know you want me to stop seeing others, but can't you all just get along? Fix the bug for Valentine's Day!

  • istrakhov Ivan (@istrakhov) reported

    @SlackHQ suddenly unable to view my muted channels in the latest iOS + app version. Reset cache too, still not working. Help?

  • saurabhd04 Saurabh Deochake (@saurabhd04) reported

    @SlackHQ Apart from above issue, it always resets all messages back to Unread. This happens only on iOS app. iOS version: 15.4 Slack version: 22.01.30 (421197) Thank you!

  • PicsPlz Oskar Ojala (@PicsPlz) reported

    Anyone got any idea why @SlackHQ keeps mixing up profile images on first load? It’s mildly confusing to see the wrong image next to someone’s name and this issue has persisted for a while

  • MelleWynia Melle Wynia (@MelleWynia) reported

    So, team @SlackHQ . I just updated to the Pro version because we need it quickly to solve a few issues, only to find out the Slack app will not enable Pro for me and my collegeas for the next 15 minutes. That's a poor UX for somebody who has just made a big commitment!

  • naturaltonic DSB (@naturaltonic) reported

    @SlackHQ I keep hearing my CPU fan spin up, and when I check in top there's a browser process pegged at 100%. Invariably, killing it brings down the one tab with a Slack instance. Any idea if this is going to get fixed?

  • xethorn Michaël Ortali 👨🏼‍💻🇫🇷🇺🇲 (@xethorn) reported

    @ndimichino @SlackHQ These kind of issues can drive someone crazy. I still have unread messages on Messenger, and I have no clue where they are...

  • slackfirstsales SlackFirstSales (@slackfirstsales) reported

    I WILL bring the entire bowtie inside of @SlackHQ first for agencies then for enterprise SaaS...Watch it go down here...

  • jeffrafter Jeff Rafter (@jeffrafter) reported

    @SlackHQ Thanks! I am using the App Store app on an Apple MacBook Air M1. I re-tested and had trouble too - the trick is to switch organizations. Once you switch the main entry focus is lost, then any keypress jumps to the thread.

  • theakirati a k i r a (@theakirati) reported

    @Twitter makes the login experience so much easier than @discord , @SlackHQ , etc. MFA on those platforms (esp Discord) is such a pain. There's gotta be a better way that doesn't involve 2 re-captchas, a one-time password email, AND an authenticator app. Yikes.
