Failed to apply patches

[lennier1]

What happened?

Occasionally, I run into an app where ipatool says "Failed to apply patches. The ipa file will be left incomplete." The resulting .ipa file can't be installed correctly. It is possible to install these apps successfully going through the App Store on my device, so they aren't unobtainable in general. I tested this on my US account. I've seen two examples so far:

com.grovemenus.WhatToEatDaily (https://apps.apple.com/us/app/what-to-eat-daily/id897669251?uo=4)
com.mmstudio.TV-GUIDEN-Free (https://apps.apple.com/us/app/tv-guiden-free/id639177792?uo=4)

Version

1.1.2

Relevant log output

ipatool download -b com.grovemenus.WhatToEatDaily -c us --purchase --log-level debug

One of the two will be used. Which one is undefined.
