Native app/browser version is not scrolling to latest message

Since a couple of days ago, new messages are not being scrolled to, and it’s needed to manually scroll down to see them.
This happens both in the native client (flatpak on linux) and on browser (firefox on windows) that I know of.
This seems related to having threaded conversations to disabled in the client (I can’t seem to repro it with threading enabled. EDIT: Not really! Happens also when threading is on).
As for the native app version: 5.12.1.
This is on Mattermost Server: 10.10.1

Any idea? Thanks!

I am having the same issue, since the 10.10.1 update. Hoping someone has a fix? I spun a new server from fresh and no issues, but the instance updated from 10.9 has issues.

Same here, server 10.10.1 updated from 10.8 (or 10.9?) and Linux client 5.12.1.

Edit: This bug is reported already, see
