iOS app motion lags when phone receives alerts or notifications from outside the app (especially SMS)

App runs smooth on computer (Mac mini / M1 2020) when testing.

Launching and / or packaging for iOS then installing via TestFlight app runs smooth until the phone receives any external notifications for / from any other app. SMS received is the worst cause.

App is a simple top to bottom scroller of moving tiles that you tap and are destroyed.

New rows are spawned from original or previous row overlapping a trigger box.

Is there some simple setting I’m missing or … ?

Your app runs smoothly on your Mac Mini with the M1 chip but experiences performance issues on iOS when external notifications, especially SMS, are received. This might be due to background app interruptions caused by notifications. Check if your app’s background mode settings and notification handling need optimization.
