  • mygiantrobot abby a (@mygiantrobot) reported

    @SlackHQ the iOS app has been so sluggish and broken lately. What’s up?

  • patrickweave_r Patrick Weaver (@patrickweave_r) reported

    Curious how many people have tried to make a /remind in the far future joke on @SlackHQ only to spend 15 minutes on a binary search to discover the year 2038 problem.

  • datagrowthpm Product Leaders Handbook - Data, Growth, ML (@datagrowthpm) reported

    @SlackHQ can you fix the bugs on the app and not try to become like teams? Therés a reason people use slack over teams and dońt try to ape them. Often have to kill the app to write to a team member as autosuggest fails

  • ajambrosino Andrew Ambrosino (@ajambrosino) reported

    @SlackHQ needs to stop with the whole usergroup:channel collision problem. @HipChat solved this years earlier and the Slack model is nonsensical

  • Lazarus_Audio Lazzie Brown! 😱 (@Lazarus_Audio) reported

    @ghoulnoise @SlackHQ Is this just when it's playing IN slack, that it gets summed down? IE when embedded? Or does it actually sum the file for when it's downloaded as well?!

  • Beryllium9 Kevin Boyd (@Beryllium9) reported

    @mygiantrobot @SlackHQ In fact, it failed to send me a notification properly two hours ago (an hour before that tweet) and I didn't receive it until just now. Something is rotten in app-land, and not just with the latest build version. Previous version had issues as well.

  • johnnyrodgersis Johnny Rodgers (@johnnyrodgersis) reported

    @MarkMuraski9 @SlackHQ Hey Mark – we're working on the mono issue and intend to preserve stereo / characteristics of uploaded audio files. I'm sorry for the trouble. Are the transcripts an issue? We are transcribing all uploaded/clip media for accessibility.

  • tjyderrien Dr Thibault J.-Y. Derrien (@tjyderrien) reported

    @SlackHQ @FreakShreek Same issue here on Firefox 88 (Linux Ubuntu).

  • joshkimber Josh Kimber 🏗 (@joshkimber) reported

    Very minor suggestion but I think it would help people post in the right channel.... I wish @SlackHQ would display the description when you hover over a channel name.

  • m_lizzy Meaghan Elizabeth (@m_lizzy) reported

    Help me @SlackHQ! Out of nowhere today, my Slack notifications (which are set to the Ding tone) suddenly started alerting me with the iOS tri-tone 😩

  • StopTXSuicides Stop Texas Suicides (@StopTXSuicides) reported

    hey @SlackHQ - we're trying to get through the help portal and it's not responsive - something going on?

  • Pei_Sze Pei Sze Wong (@Pei_Sze) reported

    @SlackHQ I have this bug on the app, on one specific channel where the notification badge will not clear away after reading the related messages. It appears to be stuck on unread even viewing it multiple times. Can you fix please?

  • drbrain Eric Hodel (@drbrain) reported

    Broken @SlackHQ struck again! I was looking for a coworker with a common name and slack wouldn’t show them amongst all the other people with that name I found them on GitHub, found their team, went to that channel, through the users, and now can search for them

  • dogehold055 X (@dogehold055) reported

    @SlackHQ Hey @SlackHQ audio microphone and video are not sync in recorded clip! Big delay Damage! and video upload is taking a long time (internet speed 10go up/down on my side)

  • LeaKissner Lea Kissner (@LeaKissner) reported

    Hey, @SlackHQ folks, I'm not sure how else to file a bug for this, but Magic Link sign in seems to be broken. Password works. Pretty please fix. (I've got an Android phone, using 2FA through an app. Other folks tell me they have the same issue.)

  • IShenfeld Inbal Shenfeld (@IShenfeld) reported

    Help needed, #startup #Marketing gentle people. Is there a way to get data from the MS Teams store or the @SlackHQ store about a product?

  • lauralloyd laura lloyd (@lauralloyd) reported

    Super annoying that you can't hyper link using command K in @SlackHQ PLEASE FIX THIS

  • dedward11 Deborah Edwards (@dedward11) reported

    @SlackHQ How can I use Slack on a browser in my phone? I can't update my OS and as of today, I cannot use my Slack app. HELP PLEASE!

  • some1else Srđan Prodanović (@some1else) reported

    @SlackHQ The knowledgebase looks really good! Though the UI surfaces a lot of the filtering abilities as is. My issue was having sort order carry over from a fringe query & having only perfect matches in results (i.e.: search for "front" doesn't match messages containing "frontlight").

  • FreakShreek Shreek (@FreakShreek) reported

    @SlackHQ I am on Firefox Version 92.0. And Slack mac app crashes my Macbook pro, what's the fix for that?

  • lookitsamdawg Amy Renkel (@lookitsamdawg) reported

    @SlackHQ I think my "unread mentions/more mentions" jump link is broken. Help?

  • accidentalflyer ah* 🌁🇨🇦🇹🇼🚀✈️ PhD Engineering (@accidentalflyer) reported

    @SlackHQ Bingo, that was the issue. Not sure why macOS update changed that. Thanks.

  • Pei_Sze Pei Sze Wong (@Pei_Sze) reported

    @SlackHQ Hi! It’s on the mobile app on my iPhone and I’m just updated recently to ios15 and same problems still

  • Dovla Vladimir Bogdanic (@Dovla) reported

    @SlackHQ your notifications are so utterly broken it's embarrasing. Why do I get a mobile notification of a message I already read 2 times on my PC...3 days ago

  • m_lizzy Meaghan Elizabeth (@m_lizzy) reported

    @SlackHQ I even updated to #iOS15 hoping this would fix the glitch. Despite all of this, I’m still stuck with the two-tone 😩

  • davecykl dave cykl (@davecykl@mastodon.social) (@davecykl) reported

    Why is the @SlackHQ account login process so annoying? Every time you need to add Slack to a new browser, you can’t just login once and see every workspace you’re a member of: no, you have to remember the URIs of each of them and login to them all individually… 😠

  • steph_c113 Stephanie C (@steph_c113) reported

    @SlackHQ I had trouble with my password. But deleting and reinstalling the app has worked!

  • michaelfreedman Mike Freedman (@michaelfreedman) reported

    @LeaKissner @SlackHQ I have that same problem, especially around 2FA.

  • mzauk mwanza (@mzauk) reported

    @SlackHQ since the iOS 15 update Slack no longer remembers my notification sound and simply uses the default sound. Is this a known issue? #Slack

  • BlueTeamJK Jason Keirstead (@BlueTeamJK) reported

    @SlackHQ Is there some way in slack to see a list of last-replied-to channels? I am always having large issues finding the channel I was chatting in 5 minutes ago in my massive list.
