I play on a PC or an iPad or an Android device and the only real niggle I have on the iPad is that when sending messages they cannot be addressed to the "club" ( as they can on the PC) but only to "private" "table" or "lobby". I think this is the same on the Android device (but I haven't used that for a while). I play in the ACOL club and when a partner leaves the table it would be nice to be able to broadcast to the club asking for new players. It's annoying to have to ask other players to broadcast for you. Apart from that one niggle I have no problem with the functionality.
