Have not played this on my phone or iPad, but on my appletv, the game loses input from the touch pad, so you can't place a cue ball or apply english, and exiting the game and reentering doesn't fix it, it will come back when it wants to. Needs fixed!
Update: now the game won't even recognize the touch surface of the Siri remote, one star until you repair this! Yes, my remote is fully charged! Yes, I've forced the game to close and restarted the appleTV too, nothing fixes it anymore
