I have no unread notifications on Slack but still shows
I used the clear all unreads shortcut (shift + esc) and it doesn't go away...
Edit: For anyone having this problem, I'm using GNOME desktop environment and clearing the notifications on the shell removes the bubble on the app icon. Thanks to @EmasXP for the hint.
You seem to be using GNOME, right? The dash shows number of notifications in GNOME, not what the app actually reports as number of notification as Slack doesn't have any integration like that on desktop Linux. What you need to do is to clear your desktop notifications history.
Thanks, a previous reply hinted at this as well and it worked. It's a shame it doesn't sync, I used discord and other apps and they all sync properly. I edited my post accordingly.
I think this happens when there's notifications from Slack in the notification center. For some reason it does not seem to sync. Clearing in the notification center is probably going to "fix" the badge counter
I haven't encountered that issue, but I hate it that it gives me a count of bookmarked posts on Slack unless I archive them. I don't need a little 12 by that tab. It doesn't help me in the slightest. What is the point?
