Latest outage, problems and issue reports in social media:

  • JanDrake Jan Drake (@JanDrake) reported

    @SlackHQ I love your product but (on Mac) I am getting extremely tired of multiple update requirements for me to enter admin password. These things not only INTERRUPT my workflow by taking focus away, you apparently can't seem to just have one update instead of 5+. Fix?

  • JanDrake Jan Drake (@JanDrake) reported

    @SlackHQ And when I say Cancel (because I'm trying to get work done) .... you pop the bloody thing up every minute or two which just make me shut it down.

  • ananayarora Ananay (@ananayarora) reported

    @SlackHQ is going to get someone fired someday because of their terrible notification system

  • AgentAkki Akshay Bakshi ✊🏾 (@AgentAkki) reported

    @jareddipane @crackberrykevin @SlackHQ Gotcha - where are you seeing this bug? We have an issue in DMs that should get a fix later this month.

  • BrandonBloom Brandon Bloom (@BrandonBloom) reported

    Deleting / marking reminders as complete in @SlackHQ has been unreliable/broken for at least 6 months. Support told me was a known issue like 5 months ago.

  • EvHaus Ev Haus (@EvHaus) reported

    @shellscape @SlackHQ Yeah it's been this way forever and it drives me nuts. What's worse is that now I'm used to it and if they ever fix it, I'll be back to accidental sends again.

  • AgentAkki Akshay Bakshi ✊🏾 (@AgentAkki) reported

    @jareddipane @crackberrykevin @SlackHQ DMing you for logs/screenshots. I wanna make sure we fix this.

  • harrisonjohnson Harrison Johnson (@harrisonjohnson) reported

    @scottastevenson @SlackHQ big fan of only showing unread! “I see too many channels in the left nav” is a fake problem

  • LemonyFelon Bait Snatching Trash ♿ (@LemonyFelon) reported

    @SlackHQ Well I have no clue why but they're back to normal now. Problem solved?

  • pezadis Adis Pez (@pezadis) reported

    @iamshackelford @SlackHQ Rules are there to be broken! #anarchy

  • scottastevenson Scott Stevenson (@scottastevenson) reported

    @SlackHQ The problem with "Mark as Unread" is that I always reflexively click the unread channel, and end up having to "Mark as Unread" it 2, 3 or 4 times to keep it pinned.

  • templarian Templarian 🐘 (@templarian) reported

    @SlackHQ Threads close when navigating away from channels now. Please fix this bug, it's killing productivity! 💀

  • Ranawriter1 Rana copywriter (@Ranawriter1) reported

    @fiverr @Ritzcrackers @SlackHQ I have I'd verification issues.

  • leifdreizler Leif Dreizler (@leifdreizler) reported

    Oh man, the new @SlackHQ iOS update fixed the issue with cross-org threads not showing up in your threads tab 🎉 The threads tab would indicate there was an unread thread, but wouldn't show you which one This bothered me the just couple weeks

  • Timway4 Timway (@Timway4) reported

    1st world problem, the new @SlackHQ update is rubbish and I now I have to spend days/weeks unlearning behaviour just so that a channel section name can be a drop down menu -_-

  • patwoodsisdull pat@jawns.club (@patwoodsisdull) reported

    @SlackHQ Also just set this up with the VOIP service I use. It's basically just Slack at this point that makes it difficult.

  • scottastevenson Scott Stevenson (@scottastevenson) reported

    @SlackHQ Sorry, it’s not a bug! The problem is when I mark as unread, I reflexively click the channel again, causing it to be read, then I have to mark it as unread again

  • viion Josh Freeman (@viion) reported

    @SlackHQ My direct messages are no longer showing on the left as a list, instead now it just has a weird menu? that i have to prompt click up, how do i fix this so it was how it used to be because this is awful.

  • charleshxpe Charles Hxpe ☘️ (@charleshxpe) reported

    @SlackHQ I contacted your support team and they recognised the issue. It happens with large images. They recommended using images 500x500px or less. That works. But with large images it crashed.

  • sharontakes Sharon (@sharontakes) reported

    @AgentAkki @crackberrykevin @SlackHQ I’m on 23.01.40 right now, maybe the latest will fix it!

  • Jack__Lancaster Jack Lancaster (@Jack__Lancaster) reported

    @SlackHQ Question wasn't how long it takes. Question is how that is an acceptable service level? #Slack

  • awesometareen Waqar Malik (@awesometareen) reported

    @fiverr @Ritzcrackers @SlackHQ Fiverr app isn't showing file attachment in inbox. Please fix this

  • JanDrake Jan Drake (@JanDrake) reported

    @SlackHQ Horrible UX experience.... this is a problem that Microsoft solved back in the early 90's when people were complaining about interruptions in workflow from apps that didn't have the focus.

  • abbaskins Abbas (@abbaskins) reported

    @SlackHQ can you please fix the joining huddle issue on the iPhone mobile app? I get a huddle request from another user. I click to join. Instead of join their huddle, the app launches a new huddle and invites them to join. This happens every time, consistently.

  • jsillyman22 Jessica (@jsillyman22) reported

    @SlackHQ Exactly! Our team built out an “internal help” workflow. If the wrong person clicks it , following steps would only be sent to them (per the way we want it to function) but they cant unclick the “claim” button

  • a1pesh alpesh (@a1pesh) reported from PETROL BUNK ORR, State of Karnataka

    @SlackHQ Mobile data was the first thing I checked (obviously) amd this is happening constantly, search and tagging is broken for last 4 days and haven't successfully worked. It's the case with a few of my coworkers as well, could this be android version specifi issue?

  • stegnersaurus Ben Stegner (@stegnersaurus) reported

    @C__Start @SlackHQ This annoyed me too, but you can change it back. Go to Preferences > Sidebar, then scroll down. There are a few relevant options, including separating DMs from channels, and having unread mentions at the top of the list

  • AngelInvestorUK Rishi - Investor (@AngelInvestorUK) reported

    @SlackHQ So disappointed at there customer support. What sort of company charges a client for a year upfront and then does not reply to emails. I can't recommend this company at all. Worst customer service I have ever seen.

  • AngelInvestorUK Rishi - Investor (@AngelInvestorUK) reported

    @SlackHQ I have written 4 emails to support and not one of them have replied to. You have charged me £190+ and I have stated this is in error. Can you please reply.

  • skyboundgames Skybound Games (@skyboundgames) reported

    @Skybound @SlackHQ seriously, help
