I have an iPad Air 2 running iOS 11.3 beta 5 and I had a crash while IF was on the screen. If a developer requests my logs then I’ll be happy to share them with you.
IF is running on the LATEST version that’s currently available to date.
That’s just me speculating, but I think it might be because you’re using an iOS beta version. Infinite Flight maybe isn’t fully compatible with that version.
I don’t know it’s a problem with my iPad and I really don’t want to restore my iPad to factory settings because everything on my Apple ID is here. I have to have this device’s password while entering my Apple ID.
I experienced few times as well.
Was doing long flight, then when I woke up the game is already crashed. (Not the plane, the app) happened 2 times already since the last update.
