Room shows only a single message
One of my rooms (1:1, encryption enabled) shows only a single old message and does not display new incoming messages.
On entering the room this error appears on the console:
Query error: RoomDetailError(MatrixError(Object({"errcode": String("M_NOT_FOUND"), "error": String("Event not found.")})))
The console also shows the errror EVENT NOT MANAGED
with an event of type m.room.encrypted
. This might also be related.
