Hello,
When you integrate framework linked statically, the usage is that those framework provide a bundle in which they put their PrivacyInfo.xcprivacy file. If you decompress an .ipa file you submit to Apple, you can see this bundle at the root. The problem is that the PrivacyInfo.xcprivacy files inside bundles seem not to be scan by Apple in the privacy process. Thus Apple send us issues about missing privacy.
Have you already heard about this problem ?
Probably link to what i am saying : Firebase issue #12557
Thank you very much for your feedback !
