Rooms joined a while ago are ignored when they don't have a canonical alias

[progval]

This typically happens for long-lived PMs.

I cannot figure out how to solve this.

This solves the issue, but causes rooms with a canonical alias to be shown as two channels (one named after the room ids and one after the canonical alias):

Should it work if you count 2 ppl chats as conversations?

2-people chats are just regular rooms, so yes. Typically rooms with no canonical_alias are these 2-people chats, that's why they are so common.
