Slack notifications do not work
Have you tried closing and reopening Slack app after checking Notifications >> Send notifications for: >> All activity?
It worked for me and my colleagues.
Neither of the answers/comments worked for me. Will share what helped in my case (Windows 10 x64). Might help anyone else. I had to turn off Slack's integration with Windows Action Center basically and they started to show up.
Solution:
- Press: Win + R
- Type: "slack://notReallyWindows10"
- Hit: Enter
PS, I think I did this twice.
I had quiet hours turned on in Windows. Turning it off fixed Slack's notifications. Quiet hours are only supposed to take effect from 12AM to 6AM, so I'm not sure if this is a Slack problem or Windows problem.
