Joining large rooms takes forever (and never suceeds)

[schmittlauch]

Description

When trying to join certain rooms – I suspect the issue are especially big rooms (many users/ many messages) – they are never joined successfully, the spinner is displayed forever

Steps to reproduce

• try to join a big room (reproduced with #riot:matrix.org and #e2e:matrix.org)
• join the room by clicking the Click here to join the room
• wait and watch the spinner graphics rotate
• after 10 minutes you still havent't joined the room

Update: After an hour or so, I can now read the current messages in #riot:matrix.org and get notifications for it (which is very annoying because I can't control notifications for archived rooms). The room is categorized under Archive.
But room interactions are still deactivated, I clicked the join link again and am still watching the spinner animation.

Update 2: When logging in with Riot mobile Android, I' have properly joined the rooms. But back in Riot Web I'm still stuck in the previous mode, but getting live notifications as described above.

Hi @schmittlauch - thanks for reporting; this sounds very annoying.

Can you confirm the exact sequence of events? Do you know how #riot:matrix.org ended up in Archive (aka Historical)? Did it go straight there after you tried to join? Had you previously been in #riot but left?

Thanks!

For the record I suspect we might have at least two bugs here - the (known) issue that joining large rooms can be slow (especially over federation) and a separate issue that a room that appears to be in Historical/Archiv can still generate notifications.

I indeed had joined the room before, so it was still present in the Archive section. But I just noticed that, after deleting the room from the Archive, it reappears there as soon as you select the room and end up in the room preview before joining.

Right now I can't reproduce the issue anymore.
