170MB .ipa is 800MB+ on App Store?!?

So, when I build my .ipa to submit to the Apple app store, it is 170MB but when I look at it on the App Store, it is 800MB!!! What is happening and what can I do about that? I am using a resources folder for loading in-game items on the fly, but that might be max 70MB uncompressed. Why in the world is my app so bloated on Apple? On Google Play, it's big (~200MB, including my .obb file) but nowhere near the bloated Apple version. Did I do something wrong with this app?

 

Seriously, WTF??

 

Do you use same texture compression settings for iOS and Android?

 

It could be just the compression algorithm doing the work. You can export the IPA file from your archive and decompress it like a zip file (because it is) and see what the app bundle size looks like.

Did you find the problem?
I am facing the same issue.

 

Solution: Don't use the Resources folder, as the improper use of the folder can bloat the size of a project’s build.
