Due to an accident that killed my MBP, I lost the latest version of an app I had under development, specifically some html support files in the package. I have backed up my iPad that had the newest version of the app on my new MBP running Catalina, and would like to find a way to extract the app .ipa, .app or whatever from the backup. I am able to extract the file I need from somewhat older .ipa packages I have at hand.
I cannot upload this app from the device using Configurator 2, and the ipa is also available on TestFlight, just not for download on the Mac.
Note this is not an app I can restore via the App Store.
