@inlesco the image properties issue is narrow - just the embedded app launcher icon images. The ‘exp’ deployment tool doesn’t have a safety check yet for app launcher icons. I checked recently. At this time, it’s do-it-yourself safety checking for iOS app launcher images and the ‘exp’ tool. Check for no transparency. On, iOS transparency is not permitted with app launcher icons.
iOS app icon guidelines:
Because each app store has different guidelines, I recommend going with the lowest common denominator (lcd), iOS. Google Play’s app launcher icon requirements are different. Amazon’s are a little different too.

Amazon’s App launcher icon guidelines:
iOS, at this time, is the lcd because of the no transparency requirement on the app launcher icon. Adhering to the lcd increases the likelihood of a successful cross-platform app deployment with exp. Obviously, there is more freedom with the app icons displayed on the store listings. Those icons, the ones user sees prior to downloading the app, have different requirements so app stores ipa checkers, apk checkers, and ‘exp’ do not care about those images.
