Rooms are shown not at all or lacking information

Current F-Droid version, the episode goes like this: Launch Element, among the rooms there is a room without icon and name, instead it shows "user-something and 1234 others". Turns out it's `#element-web`, but there is no way telling at that point other than

1. Looking up the room's id
2. Cross-checking in Element-Web

Clear the cache, the room vanishes completely. I'm still joined in it, as can be seen in Element-Web. Some time later, it re-appears, now called "Empty room".

This, together with the notorious v1 state resolution bug which hasn't been fixed in over a year gives an overall appearance of randomly quitting or joining rooms on almost a daily basis.
