I am experiencing this issue with both of my kids' iPads. They both updated to 1.13.3 and now even staying on the main menu causes a crash after 3-10 seconds. The game is absolutely unusable. They can turn off their wifi and the game will remain stable but since they want to play with each other that doesn't help us at all. I have updated them to the most current iOS available and that has had no effect on the problem.
Ironic since 1.12 was stable and the release notes for 1.13.3 said they fixed many iOS crashes.
Would it be useful to extract some of the crash dump files from their iPads? Or is this basically a known issue at this point?
Strangely enough, both of my kids' iPads are still on 1.13.3 and the crashing stopped a couple of days ago so there must be something server-side that was done to correct it. I'm afraid to update to 1.14 in case the crashing returns since there's no way to go back.
