Help/Support Error when thinning ipa's binary

[Enoch 18.9k iPhone 11 14.7.1]

I decrypted an app named RiseofKingdoms and renamed the decrypted version to RoKDecrypted. I used bfdecrypt to decrypt the ipa. 

However, when I load it into armconverter and attempt to thin the binary I get "Error occurred while thinning the binary. Contact Us for help." There is one post on here where someone had the same issue but it was from like 2015 or something.  I saw that in iOS 9 you had to download the ipa from iTunes and I'm not sure if that's still the case here in 2019.

I'm currently on iOS 12.4, iPhone 8.

If you downloaded the game from your iDevice, the app will only contain the portion that is compatible with your device. In your case arm64.

So there is no need to thin the binary since it contains arm64 portion only.

Yeah, thinning binaries is old school. People just hack ARM64 portions now.
