Annoying Piece os S#it!
★★★★ Ari Lemmke 6/23/2026 v26.06.30.0
Notifications are problematic. Have disabled all notifications. Have a gazillion comm apps. Channels constantly cause notifications. Have a huge amount of channels. Lots happening. Cannot enable just the channels I want. So I have disabled ALL notifications. And people inform me using sms or Google Chat that I should check a message in Slack. And this is my work related... please invest coding for better notification setup: not all the stuff using one conf.
★★★★ Dance Foxks 6/22/2026 v26.05.10.0
have to work here 0/10 wouldn't recommend
★★★★ prashant “prashant palani” palani 6/22/2026 v26.06.30.0
please include noise cancellation even using headphones we can hear all other noise surrounding
★★★★ Scott Lewis 6/18/2026 v26.06.20.0
Android version is a mess - terrible search, unreliable attachments and blank screen when swapping between conversations.
★★★★ Manchit Deshpande 6/18/2026
This app is not compatible with my phone Redmi Note 5 pro. Also the Chrome version cannot be logged in without the app. So it's a deadlock for me. Either make app compatible with this phone. Or else provide login with email option in the web version of the site.
★★★★ Johnny Spicer 6/17/2026 v26.06.20.0
total chaos to install a calendar besides Google and Outlook. there's so much going on here: it's so hard to work with and figure out what's going on that my small team is frustrated. We have a paid version and I think the service and working with is like having two left thumbs. I see this for enterprise and large business; but not for a small team that needs a few features like a calendar besides Google and Outlook that allows one to see ahead of what's happening today.
★★★★ Mez Pahlan 6/17/2026 v26.06.20.0
Why can't I sort my channels in their categories by last accessed? I can do this on desktop. Mobile is supposed to be easier not harder.
★★★★ Claus Lohmar 6/17/2026 v26.06.20.0
wrong mic
★★★★ Brayden McArthur 6/17/2026 v26.06.20.0
Says password is wrong so I reset. Then says I tried too many times, try again later. I have work to do, get out of my way Slack.
★★★★ Trollseidon 6/16/2026 v26.06.20.0
Navigating the app is super confusing and unintuitive. Notifications almost never work no matter what settings I apply to chats causing me to constantly miss really important messages. Another company I have uses Teams which also has a massive list of issues but at least Teams is easy to navigate and gives me notifications.
★★★★ Maya December 6/14/2026 v26.06.10.0
Don't like it. I'm forced to use it. But if I had a choice I would delete it from my mobile.
★★★★ Serhii Sakal 6/13/2026 v26.06.10.0
sred dot notice won't go away, but can't find any remaining reason
★★★★ Swarnabha Das 6/12/2026 v26.06.10.0
too much bugs in recent updates
★★★★ Lee 6/11/2026
Notifications are not showing up at times. This has been ongoing for at least a week with others reporting the same issue online.
★★★★ Alan 6/10/2026 v26.06.10.0
Are you ever going to fix the need to hit back twice all the time!!??!! Please fix this.
★★★★ Sven Hartjenstein 6/9/2026 v26.06.10.0
Logging of my account doesn't exist or is completely hidden. Logged on with the wrong account, now it takes me forever to find a log off. That is the first thing an app developer has to do, create basic login logout functionality. How can you miss that! Worst app I encountered this year.
★★★★★ Arthur Lees-Rolfe 6/15/2026
lousy that channels cannot have caps. docs cannot open in native application
★★★★★ Zachary 6/14/2026 v26.06.10.0
Glichy doesnt always show threads. Way too many quiet notification sounds. Way to many notification settings. poor layout.
★★★★★ Jeffrey Arcand 6/14/2026 v26.06.10.0
slow and buggy
★★★★★ Ryne Lyons 6/10/2026 v26.05.40.0
the settings are goofy and hard to figure out for pausing notifications something it automatically does that i dont want it to do
