I am not sure if this fix also affects the #Android clients. I installed #Element and #FluffyChat from #FDroid too.
Here the rooms issue is different. The #Element app misses 8 of the rooms I'm in. I just discovered that pressing the upside-down antenna icon on the right in the toolbar (don't know what this is named) shows me an unsorted list that has missing rooms in them.
The #ForgeFed room on #Libera chat is one of those missing on Rooms tab
