No rooms founded on android build

Hello there! Updated PUN to latest version today (1.80). I have my game combined "PC + Android" builds (imagine PC car racing game with dashboard displayed on mobile device). And currently my android version says "0 rooms founded". If I run it in editor (and +1 separate window) - everything is fine, 1 room founded. Is it a bug ? also, in previous PUN version "room.name" started to work in weird way - gave me something like "ryuig4-245jg2-fssdf4" instead real room name I used (again - only on android build - if I run same on PC in debug - everything was fine). Thanks for any advice !

my code to create room:
RoomOptions roomOptions = new RoomOptions() { IsVisible = true, MaxPlayers = 4 };
roomName = "SEAT - 1";
PhotonNetwork.CreateRoom(roomName, roomOptions, TypedLobby.Default);

this says "0 rooms":
int n = PhotonNetwork.GetRoomList().Length;
