Hello,
This morning I have been trying to do some flights on IF and my game crashes every time I spawn into an airport with 5+ other aircraft. I have tried changing some settings, but this has never been an issue before. Thanks!
Have you tried lowering aircraft count to low in settings? It takes up some processing power if the game is showing a lot of aircraft at once, especially in high traffic areas like EGLL/KLAX. Alternatively, reboot your device after every flight. This ensures it is running at peak performance.
My device does this every once in a while, I would try first restarting the app and then restarting your device.
