Hey guys, having this problem too on a published app:
https://itunes.apple.com/us/app/paper-plane-games/id1051849969?ls=1&mt=8
https://play…com/store/apps/details?id=com.markrosas.games.paperplane
Works perfectly on my iPhone 6 and Nexus 9, has problems on 5s, older ipads… it is “open beta” to help test
Any updates?
