Will you send logs?

Yes

Confirmed, seeing this a lot (especially when the chat room has threads, I think)

[klochowicz]

I can confirm that it happens routinely to everyone on our project, and started happening when we enabled threads.

In the same way, if I click "mark messages as read" in a channel, they go back to unread within a few seconds 😭 notably the unread count can bounce back to a different number every time (numbers from today: 1, 7 , 4).

If you're going to state you're having the same issue then please also send what version you're using and logs.

Confirmed, also happens to us on Element Web 1.1.37 (and previous versions) ever since we enabled threads. (Sorry for no logs.)

If you're going to state you're having the same issue then please also send what version you're using and logs.

I'm sorry for not providing logs, it actually started working amazingly well with the recent updates when I tried to reproduce it again (even the threads get read after clicking 'mark as read').
All in all, everything works fine on my macOS client (1.11.39) now ❤️‍🔥

If I ever encounter this issue again, I'll gather the logs and open a separate ticket.
