Why do apps suddenly open on newest message instead of inbox or where I left them?

A while ago I noticed a new behaviour of my phone regarding the opening of messaging or email apps. It used to be that they would open on either the inbox or where I last left them. Now they all seem to automatically open on the newest message I received.

This ruins my workflow since most of the time I now have to first click away a low-priority message to get to a view where I can see which messages actually require action on my part.

It is also super annoying when I am in a conversation on one channel and close the app to look something up elsewhere, and then end up in a different conversation when I come back a minute later.

Is there any way to fix this? I would be so greatful!!
