App rejected for being unable to log in with Apple, using Spotify API

Hi everyone. My app "FriendActivity for Spotify" is a third party app that uses the Spotify API. As such, I need the user to log into their Spotify account. This has been going well for 3 years, but today, I got rejected trying to push an update.

The reason is: "Unable to log in with an Apple account". This is because if you attempt to log in with an Apple account that isn't connected to a Spotify account, Spotify sends you back to the login screen, stating that no account associated with your Apple ID was found.

I understand that the Apple store reviewers want a smooth experience where it should have automatically created a Spotify account, but this is out of my hands. It is completely unreasonable that my app is held up but the official Spotify app as well as the 1000s of third party apps are on the store, considering all of us share the same login flow decided by Spotify. It is completely irrational. I have replied with similar messages on the App review page, but the store reviewer keeps sending me the same rejection, copy pasted. I truly do not know what to do. This update was an urgent bugfix, as my user's haven't been able to access my app for the past week.

Any suggestions recommended.

Thank you for your post and appeal. We're investigating and will contact you in App Store Connect to provide further assistance. If you continue to experience issues during review, please contact us.
