Believe this started last night or this morning but notification badges are not clearing in the iOS app after messages are read.

I'm having the same issue

Same with me

same here

I'm seeing this as well, will send an extra notification about this to the devs.

Getting the server working correctly after scaling up to the influx of new users, is one of their main priorities these days. So some stuff might be going on for the next hours/days.

we're currently working on this, should be resolved today or tomorrow

Or it could even be resolved right NOW
