  • flhoest Frederic Lhoest (www.lets-talk-about.tech) (@flhoest) reported

    @dheeraj @SlackHQ Me neither, no issues on my side.

  • PraneetaMhatre PraneetaMhatre (@PraneetaMhatre) reported

    @SlackHQ That fixed old notifications, but I am still having this issue for all new notifications that come in.

  • keenakeena123 Keena Machina (@keenakeena123) reported

    @chriskelvinlee @jack @SlackHQ This is our problem as well. I can’t convince employees in the field to reliably use anything else for photo uploads and daily communication.

  • whodeeneee whodeenee (@whodeeneee) reported

    @IamNomad @jack @SlackHQ Rocket chat is free self hosted slack clone.. have been using for years without an issue 👍

  • PraneetaMhatre PraneetaMhatre (@PraneetaMhatre) reported

    @SlackHQ Is there a fix ?

  • iantien Ian Tien (@iantien) reported

    @jack @SlackHQ Mattermost CEO here. I haven’t seen Slack replaced by IRC. There’s not a lot of Slack to Mattermost either, tbh, as they’re both IRC-based. However there is more and more Slack replaced by MS Teams tops down, then Mattermost deployed for technical and operational teams.

  • SeeTwoGaming C2 🇨🇦 - Fact Checker (@SeeTwoGaming) reported

    @slashdot The problem is that Teams' UX is clunky and laggy at best. Discord is fluid AF. I'd take @teamguilded or @SlackHQ way before Teams

  • jonathangosper Jonathan Gosper (@jonathangosper) reported

    As much as I love the jazz waiting tune @SlackHQ needs to fix the lack of ringtone when Huddles are started.

  • gaatoEth gaato.eth (@gaatoEth) reported

    @jack @SlackHQ Help me Jack.

  • romeobellon Romeo Bellon (@romeobellon) reported

    @jack @SlackHQ The problem with Slack & similar is the form of the information flowing (unstructured & lost in history). I'm trying to solve this with @getisla, a ticketing system for individuals and teams: context-rich requests, no back-and-forth, easy filtering and search. Give it a shot!

  • PraneetaMhatre PraneetaMhatre (@PraneetaMhatre) reported

    @SlackHQ I am having issues with slack notifications for past 2 days on my desktop app(Mac app, version 4.29.149) . Messages I have read and responded to still show as unread. Not a problem on browser, but mobile app is also having same issue.

  • stevetursi Steven Tursi (@stevetursi) reported

    @SlackHQ Weak network, strong network, weak wifi, strong wifi, try again, delete and retry, wait 15 minutes and try again, always the same. This is slack's problem and it happens all the time.

  • d3zd3z David Brown (@d3zd3z) reported

    @SlackHQ Thanks, realistically, I'm an admin on a few Slack instances. And, if someone has problems with their mobile app stopping, I'm guessing they will figure that out on their own. I'm just wondering what the purpose of the email was, if it has no information in it.

  • elhipernauta hachyderm.io/@elhipernauta (@elhipernauta) reported

    @jack @SlackHQ Looking for a new company where you can help bully thousands out of their lifeline?

  • rot13maxi Rijndael (@rot13maxi) reported

    @jack @SlackHQ I used to work at a large company that maintained IRC as back-up comms incase everything else was down. A bunch of folks hung out there as the preferred place _anyway_.

  • Btc_eth_dog Thank you (@Btc_eth_dog) reported

    @jack @SlackHQ do the world a favor make a donation to me 1 dollar 5 dollars 10 dollars help me with whatever comes my money is gone I am in a very difficult situation thank you everyone in advance God bless everyone 👇(usdt trc20)👇 TFvz5ZcR76jcXRzv5VpyfUVVegfGcHXQy9

  • SandyCanetti Sandy Canetti (@SandyCanetti) reported

    @hpoom I agree. I was driving to a meeting in New York and ran into a traffic accident on I-78 that delayed me a half hour. Didn't have contact numbers for the people I needed to reach and slack doesn't work with Android Auto. @slackhq needs to fix this already.

  • domknight Dom Knight (@domknight) reported

    @jack @SlackHQ Buy and fix twitter and I’ll try it

  • max_zaichenko Max 🇺🇦 (@max_zaichenko) reported

    @jelleprins @SlackHQ The telegram support team is so bad. A lot of space for the scammers support team, do not do anything with that issue. @telegram

  • iman_sadeghi87 Iman Sadeghi (@iman_sadeghi87) reported

    You get one computer issue rectified and then you can’t use @SlackHQ cause your old account was deleted.

  • Vp6685local Vinh pham (@Vp6685local) reported

    @jack @rot13maxi @SlackHQ Jack help me man. Been trying with cash app support team over several months now. They’re keep sending automated messages that they can’t verify with information provided. Been over a year can’t buy or sell or taking my money out

  • shecankickitt ella (@shecankickitt) reported

    @SlackHQ Tried it but not working. My problem lies in my slack app on my desktop. Before, I can still hear the knockbrush sound everytime I'll receive a new message even if my slack app is minimized. Now I can't hear it anymore, it's just a very low tick sound even tho my volume is full

  • sarru001 AS (@sarru001) reported

    @jack @SlackHQ @SlackHQ is trying it's best so people switch to another app. That stupid app is having issues every day

  • cgovias Chris Govias (@cgovias) reported

    @SlackHQ navigating a PDF (moving from page to page) is the absolute worst in the desktop client. Why can't I use my arrow keys? Or even Pg Up and Pg Down? y u do this slack (Yes, PDFs are also the worst, but c'mon)

  • Grimm66648 Grimm (@Grimm66648) reported

    @jack @SlackHQ I’m not sure, but I just watched that Matt Lauer interview you did back in 2016. Wow, did you turn out to be the biggest liar. You are a huge part of the problem we have in this country.
