Since the error only occurs from TestFlight and App Store, I can't really use the console to see what it is at the moment.

Yes so, it's exactly the second thing you said, it's not about the notifications. The problem is that the same shared records that are fetched from the Xcode version without any problems are not fetched in Production.

Thank you for the suggestion! I did them from code however, not dashboard so I believe that isn't the problem for me. I've also deployed my container to Production already.
