@SlackHQ Lately Slack has been really bad at failing to notify me about things. The Windows Slack client just seems to fail to update while in the background pretty often and the Android app (on Pixel 4a) also seems to fail to send notifications at times as well.
We hear you. Apologies for the delay! We're working to improve Android push notifications right now, so hopefully you'll see improvements on that front soon. As for your desktop app not showing the notifications/badges until you manually look, that's odd. 1/2
