It’s seems to be an apple / Facebook thing.
iPhone 6s / ipad4
It loaded on android. But supper slow on kids phone.
It’ crashes as it loads 90%
Iphone6s and iPad.
I tried: a full restore. Same thing. Crash.
I tried: free storage space, network, reboot.
If I reinstall app it will work. When I then connect Facebook. It crashes.
Been playing for nearly a year. No problems. Just in the last week.
