Latest outage, problems and issue reports in social media:

  • 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

  • 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

  • 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!

  • 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.

  • 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?

  • 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?

  • 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 😔

  • MissGenevaG Geneva (@MissGenevaG) reported

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

  • 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)

  • mygiantrobot abby a (@mygiantrobot) reported

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

  • 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

  • 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

  • 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?

  • 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 😩

  • 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 😩

  • 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

  • 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.

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

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

  • 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… 😠

  • lookitsamdawg Amy Renkel (@lookitsamdawg) reported

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

  • 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").

  • 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.

  • 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.

  • 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.

  • 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?

  • michaelfreedman Mike Freedman (@michaelfreedman) reported

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

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

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

  • 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
