very important. I accidentally hit "mute 1 hour" on the android notification and I can't seem to undo it. I desperatly need notifications for that!! Got someone that needs to give me real time updates on a sitiatuon! This should never be there.
For a user channel, press and hold on their profile icon and options should appear at the bottom of the screen, press 'Unmunte'.
For a server, when you have selected it and the channels in the server are onscreen, tap the three dots near the top right of the screen, next to the title of the server and then the notifications icon, from there you can change the setting for that server.
I do certainly agree that this is a dumb feature and should be removed or at leased moved into Discord's settings, not placed where the usual reply button would go!!
