  • GDavisDevOps Glenn Davis (@GDavisDevOps) reported

    @SlackHQ Is there a way to add a Border to the Windows 10 Main Slack Window? It seems like Slack ignores the Windows 10 Border Personalization I added. The white background blends into my other windows and makes things very confusing. Thanks for any help.

  • kurtseifried Kurt Seifried (He/Him) (@kurtseifried) reported

    @briankrebs Also SSO generally doesn’t allow it. Also renaming email accounts can result in some really painful and not well defined problems with some services. @SlackHQ I’m talking about you.

  • emanuelcinca Emanuel Cinca (@emanuelcinca) reported

    @westwoodpro We're seriously considering giving up @SlackHQ actually. Too many bugs they never fix, and too many alternatives. Next week, we're doing a full "Slack-free" week to see if we need it or if we just got used to it.

  • xlamide Olamide A 🚀🎮 (@xlamide) reported

    @SlackHQ please fix your Huddle issue on mobile. Please

  • michaelbolton Michael Bolton (@michaelbolton) reported

    On the iPhone, @SlackHQ’s search fails to find the name of a person in a team; a person with whom I’ve had conversations. Another of those widdle bugly-wuglies—the kind for which @SlackHQ posts those annoyingly cutesy bug fix reports.

  • keithjgrant Keith J Grant (@keithjgrant) reported

    if "confirm your email address" e-mails are part of your login process, you sure as hell better send that email faster than 10 minutes @SlackHQ 🙄

  • iamjan___ JAN (@iamjan___) reported

    @SlackHQ horrible horrible customer service. We have a company emergency and whomever Aine is on your team needs to be fired!

  • Humanstein Nathan (@Humanstein) reported

    @SlackHQ 2 TikTok issues: TikTok links have not had an unfurl or preview inside the mobile app for months now. The app also frequently tries to open those TikTok links in the browser and my users have to click the Open In App button on the page after it loads in the browser.

  • ritvik2700 Ritvik (@ritvik2700) reported

    @SlackHQ The main issue is If I set my time to Central Canada and save it while I am in India. It gets saved and what I view on my profile is that time and timestamps working according to that time too. But if my TM sitting in Canada views my profile they see my India local time.

  • unfunfionn Fionn (@unfunfionn) reported

    @SlackHQ @gersongoulart Are we any closer to seeing this option? It has never become intuitive for me and it really slows me down under pressure. Start a message, quickly navigate elsewhere to reference something, and the message is now somewhere completely different in the app. So so annoying.

  • josh_wills Josh Wills (@josh_wills) reported

    @pistevo @shinypb @SlackHQ Mark let's just sneak into the office on Saturday and fix this stuff real quick

  • HelpingAfghan Helping Afghanistan refugees (@HelpingAfghan) reported

    @StraightCharity @SlackHQ All of us humans live on the same planet, we must help each other to eliminate the roots of inequality and injustice. I sent messages to many of the world's rich people, such as Musk other people in the world, unfortunately but I did not receive an answer

  • fandamned4ever aish 🐇 (@fandamned4ever) reported

    @memermallu @SlackHQ pls fix 🥺

  • AJSlavin ajslavin.eth (@AJSlavin) reported

    What free subscriptions would help you run your business? @Zoom ? @twitter blue? @SlackHQ ?

  • jshatsky Jason Shatsky (@jshatsky) reported

    @SlackHQ @SlackStatus have a support question can you please help?

  • haekkatraining Haekka (@haekkatraining) reported

    The functions of a @SlackHQ app can be broken down into three categories: 1/3 Post information While the ability to post information such as a record from Salesforce or support ticket information from Zendesk, there is limited risk with these app permissions.

  • candiwrites Candi (@candiwrites) reported

    @jcolman @slack @SlackHQ This happens to me about once a year. Very annoying. The only fix I’ve found is a full uninstall and reinstall.

  • adamromano Adam Romano (@adamromano) reported

    @chelseaa_t @SlackHQ don't worry it was a content issue.

  • GeorgeSiosi George Siosi Samuels (@GeorgeSiosi) reported

    Problem: ppl often forget to Thread Reply in @SlackHQ parent channels Solution: add a subtle box under each message in parent channels/messages that says either… A: Be the first to reply B: Reply to others in thread This would save me from reminding ppl all the time 👀

  • MOHAMMEDSAID232 Mohamed Hamed (@MOHAMMEDSAID232) reported

    Why there isn't any bot that we can ping, hey is slack down? And it replies by yes or no @SlackHQ

  • oyatoyinbowunmi oyatoyinbo wunmi (@oyatoyinbowunmi) reported

    I need someone to sit me down and teach me how @SlackHQ works 🥺

  • perkelix Martin-Éric Racine 🇫🇮 (@perkelix) reported

    It would be a good idea for @SlackHQ to fix its automated e-mails. If someone posted something to the whole group, they have NOT mentioned me.

  • cytoskeletown Jessica Henty-Ridilla (@cytoskeletown) reported

    hey twitter... help me out... what is the longest real @SlackHQ thread you have ever heard of... asking for a friend... don't come at me unless it's over 10k.

  • AngelM3ndoza Angel Mendoza (@AngelM3ndoza) reported from Madrid, Comunidad de Madrid

    @fiomtec @SlackHQ they need that fix

  • fguille94 Guillermo Fernández (@fguille94) reported

    @SlackHQ @davidbarryhill I just googled free-***** slack and this tweet showed up, when we're invited to calls in slack, we get a notification on our phone with a slack url containing free-***** in the path, is that the name of the calls service?

  • BlnaryMlke Fernando 🐼 Miguel (@BlnaryMlke) reported

    @SlackHQ trying to add mfa to a newish account via ipad app and can't find a way to do it. Nor does it let me login via browser

  • Sumohax0r Marty Sullens (@Sumohax0r) reported

    @westwoodpro @emanuelcinca @SlackHQ Discord > * 150 employees a working on it for over 5 years, very little issues.

  • _StevenShapiro_ Steven Shapiro (@_StevenShapiro_) reported

    @SlackHQ has been down for 5 minutes and my world is crumbling

  • perkelix Martin-Éric Racine 🇫🇮 (@perkelix) reported

    @SlackHQ Please read again. It's not that I don't want these e-mail notifications. The problem is Slack claiming that someone mentioned me in a group when that's incorrect. Nobody mentioned me. Someone merely made a post to the whole group. Please fix that.

  • ChristineEsoldo Christine Esoldo (@ChristineEsoldo) reported

    @SlackHQ is down and remote workers everywhere are experiencing the trauma of being forced to use email to communicate. #slack
