App crashes after splash screen


My app seems to work fine most times but at some point the app will end up on blank screen after the splash on iOS. This occurs on some older devices more often. The only way to get the app running again is by open the multitasking and remove the app.

It seems to stop after all the plugins are loaded and the index file is requested. If the app is kept in this state open it will eventually crash.

Anyone has experience the same issue?
