In iOS 15.7, 5g network, when I download app, the App Store hint me the download size about 427M, if I cancel download and download the app again, it hints me download size about 115M。Why did the download size at the first time much bigger than the install size shows in App Store(247M)，I reproduce the phenomenon in another device which is also iOS 15.7, what did the app(427M) contains?
Can someone help？
