I think the /findgame command on Bedrock should function more like the /nbg command on Java. Currently, /findgame only works if you are spectating a game. If you are in a lobby waiting for a game to start, but no one is in the lobby so the game won't start, you have to go to the hub and go to the npc to join a lobby with more players. On Java however, if the lobby you are in is not filling up with players, you can use the /nbg command that will send you to the lobby of that same game with the most players. I think the /findgame command should function similar to this.
