Yeah, I'm really confused - I can literally load and close the game 5x in a row and get different results.
1. Game stuck at 0%
2. Ads load / game perfectly smooth
3. Ads don't load / game perfectly smooth
4. Ads load / game very jerky
5. Ads don't load / game very jerky
This is is all in a space of a few minutes, with no other apps open.
I'm using no external plugins, only official Construct 3 stuff.
P.S. HTML5 version and Web Apps work like a dream on devices and desktop.
