  • jasonsigal Jason Sigal (@jasonsigal) reported

    How is it that consistently, I’ll get up from my desk for a quick second after my Slack clams down for some time, only to have a colleague ping me seconds after I get up. Never fails. @SlackHQ is this by design?

  • IJohnson_TNF Ian (@IJohnson_TNF) reported

    @jen20 @SlackHQ I'm only in 5 slack workspaces but I've now got 5 logins to manage rather than one login and "linking" my account to the workspace. Even MS has an attempt as single sign-on

  • Blink4Chu Emily (@Blink4Chu) reported

    @SlackHQ sooo... the thread issue I mentioned couple of months ago, you said you were on top of it... any news? It is extremely frustrating to work with your application at this point.

  • lailavona Laïla von A. (@lailavona) reported

    Hey @SlackHQ, my red badge notifications are suddenly gone from my desktop app even though I didn't change my settings. I'm missing a lot of messages because of that since yesterday. Can someone help me get them back?

  • DrJenMurphy Jennifer S. Murphy (@DrJenMurphy) reported

    @eGeeking I told mine if they were too lazy to use an emoji in the @trainwithqic @SlackHQ I was too lazy to deal with their problem. #guildchat #useyourwords

  • lailavona Laïla von A. (@lailavona) reported

    @SlackHQ Thanks! I remembered I had this problem 6 months ago—I found my old tweet and the solution was to change the notification settings on my Mac. I don't understand why this happened again all of a sudden? I didn't do any OS updates yesterday and it just stopped working 😕

  • KiwiTheKat1 CaliKat (@KiwiTheKat1) reported

    @SlackHQ I just DM’d you the issues. It happens on my iPhone with iOS 14.3 and my iPad

  • networkgrinch The Network Grinch (@networkgrinch) reported

    @_justanotherdot @thingskatedid @SlackHQ Last time i saw my coworker do this I forced him tl sit down and do a code review on what his changes did. He now gives very detailed commit messages

  • buildstuff15 let’sbuildstuff (@buildstuff15) reported

    @Jmartens @SlackHQ @SlackHQ if only I was able to create threads on IOS (KNOWN BUG) or so I’m told by your team, just does not allow me to access the drop down menus to create threads or any other functions in that menu after posting, three months and counting !

  • SheppySage Electric Sheep (@SheppySage) reported

    @SlackHQ Hey, any idea how complicated it would be to have a linked message from a private channel unfurl for viewers who are in that channel? Lazy, "save the click to visit the channel/thread" problems. <3

  • ManyTrout Amy (@ManyTrout) reported

    @SlackHQ Is there an issue with the custom emoji section? Mine seems to have disappeared from the app (on ios 14.3) tho i can still bring up custom emojis with their :emojiname:

  • BhattadChirag chirag bhattad (@BhattadChirag) reported

    @vivekraju93 @SlackHQ Koi nahi, hota hai. Agli baar problem aaye toh ek baar thoda effort maar lena to solve it. Asking such queries on a public forum is quite embarrassing tbh xD

  • dmarinova_ Desislava Marinova (@dmarinova_) reported

    @SlackHQ @stewart I cannot rename a private channel which I converted from a group of direct messages.. clicking on "Additional Options" there is no "rename" setting... please help... thanks

  • dclpuk Daniel Pickering (@dclpuk) reported

    @SlackHQ app won't work unless you update to the latest. OK problem solved app uninstalled. Why this was in an update I have no idea lol

  • buildstuff15 let’sbuildstuff (@buildstuff15) reported

    @SlackHQ from the road after I standardised on it REALLY disappointed As the owner of a software dev company it’s a bit strange that you instantly assumed I am an incompetent user instead of checking if there were know issues

  • ChetisLove Chet Love (@ChetisLove) reported

    Our stock market is crazy. @reddit boards are causing pumping stocks like @GameStop now like 2018 @SlackHQ channels were pumping crypto stocks. The world is upside down.

  • Etha0011 Ethan S (@Etha0011) reported

    @SlackHQ I login and then I’d click a channel or message and it would sign me out and it would loop. I’ve managed to fix it by removing all workspaces and starting again but just a heads up! :)

  • buildstuff15 let’sbuildstuff (@buildstuff15) reported

    @SlackHQ Does not work on my IOS 11 and also doesn’t work on my colleges IOS 8, KNOWN ISSUE BY SLACK TEAM

  • buildstuff15 let’sbuildstuff (@buildstuff15) reported

    @ryanbigg @SlackHQ @SlackHQ I just wish I could create a thread at all after posting known bug on IOS according to your team, three months and counting still no fix

  • buildstuff15 let’sbuildstuff (@buildstuff15) reported

    @SlackHQ @SlackHQ really! How? The drop down menu does not appear if I tap my post on my IOS device? By the way a known bug on your side according to your team, three months and counting!

  • pavel_lishin pavel_lishin (@pavel_lishin) reported

    @drldCsta @SlackHQ consistently puts out features that are better for light/casual users, that are *terrible* for advanced users. Remember the whole wysiwyg thing, which they added a toggle for when enough people got annoyed? Hopefully we'll see a toggle for this nonsense too.

  • jianmingzhou Jianming Zhou (@jianmingzhou) reported

    @SlackHQ I can not not post large code block...any one knows that issue?

  • theblue_panda ThebIuepanda (@theblue_panda) reported

    @SlackHQ Yes. It has been happening for a while and I thought it was for specific pdf but after 10 months I don’t think it’s pdf format issue

  • buildstuff15 let’sbuildstuff (@buildstuff15) reported

    @SlackHQ @SlackHQ really! How? The drop down menu does not appear if I tap my post on my IOS device? By the way a known bug on your side according to your team, three months and counting!

  • drldCsta drl "kind but not nice" dCsta (@drldCsta) reported

    @pavel_lishin @SlackHQ WHO ASKED FOR THIS?!?!? I could understand a non-focused modal you could choose options from, but hijacking the input like this consistently slows down whatever I was doing

  • ManyTrout Amy (@ManyTrout) reported

    @SlackHQ Thanks for replying! I reset the cache, when that didn’t work i restarted the app, then restarted my phone. Still not working for me. When I asked other folks they said having the same/similar issue. Not a big deal just thought there may be an easy fix.

  • HeyStammann Helmar (@HeyStammann) reported

    When deleting a channel it can't be recreated. Can you fix that? Thank you @SlackHQ

  • buildstuff15 let’sbuildstuff (@buildstuff15) reported

    @SlackHQ Really surprised you don’t know@there is an issue, although maybe not I don’t get proper answers from your team other than we know about it can’t tell you anything more in@mean time slack is all but useless to me to run my team
