In tic tac toe example, I just changed line 64 as :
appWarpClient.joinRoomInRange (1, 1, false) to
appWarpClient.joinRoomInRange (1, 4, false)
and at line 88
appWarpClient.createTurnRoom ("TicTacToeRoom", ROOM_ADMIN, 4, roomPropertiesTable, 30)
And this doesn't work. What is expected is that the second client will connect to the room created by the first one. What is actually happening is, both clients are creating new rooms i.e. second client does not identify the first created room.
I have seen other posts where it is mentioned that joinRoomInRange API for corona doesn't work but could't find any substantial pointers.
