Motivation and Context

Resolves #21654, fixing a regression introduced in #21472

Description

Previously, the localized key was not used when checking to see if the app info has changed during the deliver upload step, so it was always failing to upload changes to privacy urls. With this change, we now check the current value of the app info using the localized key so that it can compare the current and previous app info values as expected, allowing changes to the privacy url to upload as expected.

Testing Steps

1. Change the privacy url in a project with fastlane/metadata/en-US/privacy_url.txt
2. Use fastlane deliver to upload the change

Thanks for fixing this. Any idea when there will be a new release with this fix? We're running into the same issue as well.

We're working on a new release, just don't know when yet 😥 you can use master branch in your setup meanwhile, to not have to wait for the release 🙏
