When is Slack finally going to fix their broken notifications on mobile? I am so pissed everytime I turn on wifi, hundreds of notifications are raping my phone and tablet. But when I actually want to get notifications on my phone (and leave PC running) I get fucking none.

I use the Desktop version while at work during day time and there is a setting which says deliver notifications to mobile as well if I don't read it on desktop for 5 min. Yet, the moment my browser window loses focus, I get notified on both desktop and mobile

And as you rightly said, while at home during night times, the mobile notifications don't work. Either the power manager on my mobile has destroyed the activity or the mobile notification doesn't work at all
