  • novackanil blee Blah (@novackanil) reported

    @SlackHQ @salesforce please add stackoverflow functionality to gamify rooms meant for people to ask questions because it's sad that I can get external help on stackoverflow faster than I can get internal help via slack, just because of pretend points.

  • dtlvan Mak Thái (@dtlvan) reported

    @SlackHQ 3. Sometimes, I cannot reply to channel or thread because of - Tap on a message, thread doesn’t show (similar to my first issue) - The composer bar disappears, there’s no way for it to display again.

  • CowboyKeeks Keeks (@CowboyKeeks) reported

    @hasanminhaj @jimmyfallon @SlackHQ My wife is in her 4th year of medical school. DO program. When she’s not at the hospital helping patients during a pandemic, she studying at home, then she goes to bed. Belittling a group of people who are dedicating their lives to help others is gross and pathetic.

  • 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 😩

  • EmanM Eman M (@EmanM) reported

    @SlackHQ @PatrickKlug I am still having the same issue. The green border sticks to my screen even till a day after the call has ended. Last version on windows 10. This is an annoying issue, when will it be fixed?

  • mvdan_ Daniel Martí (@mvdan_) reported

    Sometimes I get a push notification from @SlackHQ, but when I open the Android app, there's no message. Restarting the app doesn't help, but waiting an hour does. Now it's affecting the desktop client too. I just restarted it to see a message from last night. What gives?

  • 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?!

  • steph_c113 Stephanie C (@steph_c113) reported

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

  • 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

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

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

  • 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)

  • 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 😩

  • lookitsamdawg Amy Renkel (@lookitsamdawg) reported

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

  • dtlvan Mak Thái (@dtlvan) reported

    @SlackHQ My issues: 1. Cann’t switch channels using sidebar: after tapping on channel name, nothing happens. It got some delay & even if I taps on it many (X) times, after the channel is loaded successfully, it will be reloaded exactly X times by blinking 😔

  • 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).

  • MissGenevaG Geneva (@MissGenevaG) reported

    .@SlackHQ iOS app is really bothering me with this false “1” notification badge, please fix :)

  • BrianMakas Brian Makas (@BrianMakas) reported

    @samreynard @SlackHQ @salesforce … could also see this as great means of postings alerts otherwise done in email or Chatter: - Big sales to kudos channel - Upcoming call notice in private channel between the Engineer and Sales Rep working together to close deal - Help! Trigger message to specific topic channel

  • nskyll Nskyll (@nskyll) reported

    @SlackHQ @El_4_a In slack on ios I go to "you", "notifications", "sound", and change it, but it always uses the device default. This used to work -- how can I fix it? Thanks!

  • regameyk Kevin Regamey (@regameyk) reported

    @SlackHQ Hey pals! As of yesterday, we've been noticing that Stereo sound files shared to Slack are playing back in Mono. This is a pretty large problem for a team like ours that works remotely in the #gameaudio space. Any idea if we can expect a fix there? Thanks!

  • 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

  • AngieCoiro Radio Angie 📻 (@AngieCoiro) reported

    @SlackHQ Nope, no luck. I was able to click/drag before whatever changed changed. Refresh didn't help, brought it back the same way. Anything else to try before a (groan) fresh install?

  • 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

  • roisiproven Roisi (@roisiproven) reported

    I have to believe that @SlackHQ made the live captioning for huddles terrible on purpose, it’s completely nonsensical but has made for the funniest stand up I’ve had in a long time

  • johnnyrodgersis Johnny Rodgers (@johnnyrodgersis) reported

    @MarkMuraski9 @SlackHQ We are working on the mono issue but I would like to understand your needs here to avoid disrupting your workflow if possible.

  • AliMattu Ali Mattu, Ph.D. (@AliMattu) reported

    @SlackHQ Thanks for the tip. Deleting the app and reinstalling it from the App Store solved the problem.

  • 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.

  • 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?

  • dtlvan Mak Thái (@dtlvan) reported

    @SlackHQ I need to reset the cache using app settings in the Settings app but it won’t last. After using Slack in 30 ~ 45 mins, the issues occurs again & again.
