  • aditishekar Aditi Shekar (@aditishekar) reported

    Recently, @SlackHQ has stopped showing me all my channels on mobile. It seems to decide (haphazardly) what to show me. I have to search channels like “general” or “product” to find them. Anyone else having this issue? Whyyyy are they doing this? I miss a lot more key stuff now.

  • AnuragJagia Anurag Jagia (@AnuragJagia) reported

    Dear @SlackHQ if you can't open my desktop app after multiple login attempts & taking me to your browser where I am already logged in... at least give that "open slack" button to click which can open "the app". So irritating right at the start of a business day! Arrrgggghh

  • christiaanbrand Christiaan Brand (@christiaanbrand) reported

    @AxelNennker @Google @SlackHQ Isn’t this a Slack-problem, though?

  • muldoonx9 Alex Hoffman (@muldoonx9) reported

    I really want @SlackHQ and @discord to stop fighting on my computer cause Slack starting up stops Discord starting up on windows login.

  • oh1tr oh1tr (@oh1tr) reported

    @SlackHQ This is still broken: Windows, after huddle, VMware Workstation window.

  • harshagwalani 𝙷𝚊𝚛𝚜𝚑𝚊 𝙶𝚠𝚊𝚕𝚊𝚗𝚒 (@harshagwalani) reported

    @SlackHQ Thank you! I updated to Big Sur 11.6.1 yesterday that seemed to have caused the problem. Also updated the slack app yesterday. Rebooting has fixed it!

  • bzaks1424 Michael P. McD (@bzaks1424) reported

    Hey @SlackHQ - Airline wifi is killing me today. I know you use websockets for comms - ever considered long timeout http requests as a backup? I know a now-sibling company who can help you with the APIs.... (*cough*@MuleSoft*cough*)

  • stefandevo Stefan de Vogelaere (@stefandevo) reported

    @SlackHQ Yep correct. Even in incognito. Have same issue on two different workspaces. Adding an icon gives me after the crop option an empty page - if I do add app the allow button keeps on spinning and in the end gives me the pasted inage error

  • christovskia Chris Armstrong (@christovskia) reported

    @simon_tomes @mcgovernaine @SlackHQ My brain is a bit broken. I thought there was a SnackHQ

  • Rachel_Dillin Rachel Writes (@Rachel_Dillin) reported

    Oh dear. Slack just had a commercial on TV, and hearing the notification sound while I'm NOT working made me freak out! No thank you @SlackHQ

  • itscarson not ur mom (@itscarson) reported

    @SlackHQ dont let me down here friends @SlackHQ

  • PAltFish Peter Fish (@PAltFish) reported

    @hinasurani @MicrosoftTeams @SlackHQ You are not crazy or alone in this! Seems like every service has this function except Teams and it makes no sense.

  • tiedtiger Tadhg (@tiedtiger) reported

    @MrLeePerry I've had the same gripe. @SlackHQ should have one login and central feeds where all my DMs and mentions can be read from across my separate communities. All the flitting back and forth between the 6 Slacks I'm on drives me nuts.

  • thesupaldesai Supal Desai (she/her) (@thesupaldesai) reported

    I keep hearing the @SlackHQ notifications going off even though the computer has been shut down.

  • OrigamiUx Courtney Dunn (@OrigamiUx) reported

    Hey @SlackHQ, my work makes it so that every few days I have to sign in/re-authenticate Slack. When I do that it resets my display name. It would be awesome if Slack remembered my preferred name. I have to fix it 2-3x/week. 💔

  • ahfeminella Andrea Feminella (@ahfeminella) reported

    @hinasurani @MicrosoftTeams @SlackHQ Please can the Teams universe fix this 🙏🙏🙏

  • VerbalPugilist_ The Incontinent Disciplinarian. (@VerbalPugilist_) reported

    Tired of getting Slack notification on my phone only to open and see it was from an already concluded conversation. I've been begging you to fix this **** @SlackHQ

  • Doreltwt Dorel (@Doreltwt) reported

    @metaprinter @MarketUrbanism @SlackHQ It does not help with people responding an hour (or more) later unfortunately

  • geilt Alexander Conroy (@geilt) reported

    @SlackHQ Give us a setting so we don’t accidentally mention a person not in the channel :). Problem solved.

  • CountVice Sutur (@CountVice) reported

    @discord are you ever going to fix the HEIF/HEIC issue? It’s seriously annoying and @SlackHQ doesn’t have this issue

  • JordanHarbinger Jordan Harbinger (@JordanHarbinger) reported

    @SlackHQ wow is the /remind command clunky and terrible. We need to have a simple command that reminds us about a thread or message in X days/weeks. Not sure why the slackbot is so 'dumb' when it comes to this.

  • WuonParticle Warren Ferrell (@WuonParticle) reported

    @SlackHQ @mxmauro Any status on this fix? Finding it quite annoying during calls to have a significant portion of my screen be effectively useless.

  • TommoBedhair Thomas Bastable (@TommoBedhair) reported

    @SlackHQ Quick bug report - on iOS and MacOS there’s a bug where the app displays the incorrect profile picture for a user. It’s most likely a cell reuse issue - not setting the cells image to nil upon reuse.

  • WuonParticle Warren Ferrell (@WuonParticle) reported

    @SlackHQ Looks like I was on 4.20. updating fixed the issue. Thanks 🙏

  • jsXOver theScientificX-over (@jsXOver) reported

    @ysr1729 @SlackHQ Slack has secure messaging but isn't licensed for healthcare use for regulatory reasons. I worked on a Slack-like solution for this problem ~ 10 yrs ago and I still think it's a good solution.

  • MalindaFrevert Malinda 🎃Scare🎃 Frevert (@MalindaFrevert) reported

    @AnnaBreedlove @SlackHQ It will also SAY notifications are muted and I’ll still get pinged Plz help us @SlackHQ !

  • kwtaylork Taylor Kim (@kwtaylork) reported

    @amandahwood @SlackHQ Right?!!! I’ve been thinking a lot about the mis-aligned incentives in Tech. Every app wants to maximize the time users spend on their products. But sometimes, users need to NOT use the product. Fascinating (and ******* hard) design problems to solve for!!

  • muldoonx9 Alex Hoffman (@muldoonx9) reported

    @SlackHQ @discord I also REALLY wish @SlackHQ would respect me unselecting the "launch on login" option and not reselect it everytime it updates.

  • lamw William Lam (@lamw) reported

    @bpatvmware @SlackHQ it should force user to post in one place AND wait. I see this happening on a regular basis, it also confuses folks trying to help as you now have repeated answers/etc. Just a mess and I think Slack can do much better to improve UX Also, folks should learn how to be patient :)

  • benfryc Ben 🤖 (@benfryc) reported from Farmington Hills, Michigan

    @SlackHQ is there an ETA on a fix for double speed gifs the new iPhones?
