Intermittent white screen on iOS

Hi there,

Not sure if anyone else has experienced this issue:

One of our clients is using our app on 2 different iPhones - SE and 6S. Every so often they get a white screen when starting up the app (splash screen displays then white screen of death). Client has tested on LTE and on home wifi with similar results.

We have tested this particular build extensively and we haven’t experienced this issue and neither have other clients.

Anybody seen anything like this before?
