So @SlackHQ notifications on my Android phone used to be basically instantaneous (within seconds of the computer) but now they're coming in 15-30 minutes late (even worse than @IRCCloud notifications which tend to be 3-5 minutes late). Just me, or happening to everyone?
I'm running Android 8.1.0 (June update), with @projectfi. Maybe if I actually understood how notifications worked I'd have a better idea who is at fault...
