I also play on the iPad, I know other people who do but they don’t seem to have the problem, mine will happen at least once a game and like you said it ruins the game, it’s going to happen but you don’t know when. I have sent two complaints in but I have had no reply.
They need to go back 2 revisions to 1.71.1 and make it available to those have the problem if it’s possible, somebody said 1.71.10 works but I installed it and still the same.
Apart from the balls I have lost I had to give up on the clash and I can’t see me finishing the showdown.
