hello boxers, we have almost 35 atlases in our game and used game center, In-app purchase for remove ads and unlocking new world, for advertisements we have used AdMob interstitial (frequency=4) , Banner(frequency=1). does any of the above can cause crashes in different devices ? we are facing crash issues in some devices( Iphone 6,6+,5,5s,5c,Ipad mini). and only working properly with 6s,6s+ & Ipad pro. Atlases have been optimized and dosen't contain extra objects .
wow 35 atlases would be your problem, 3 to 4 is the common recommendation from what i can gather on from the forum. Thats a lot of atlases, your images must be huge.
im sure this is it.. do a search for atlas or atlases and you will see a lot of recomendations on how to reduce this
