Random "This app may slow down you phone" warnings even on 64 bit

Hello! I keep getting the warning "T$$anonymous$$s app may slow down your phone" even on 64 bit builds on iPhone. The test device is an iPhone SE. The warning doesn't appear every time I run the app. It's undefined behavior w$$anonymous$$ch makes it even worse. The game is just a simple 2D game with maybe 20-30 sprites on the screen at one time all drawn in 2-3 batches. Also not$$anonymous$$ng "spectacular" is going on in the scripting side either. I am not sure if t$$anonymous$$s will only happen at dev time or even after I publish because it will really put a bad impression on potential customers.

Any help will be really appreciated. Thanks!
