I have a flutter app both running on android and ios which were accepted to both markets.
To support share intent, I had to change some build settings on Xcode.
After the change, everything works well on my end (tested with the testflight version of the app).
However, the app is keep rejected due to Sign in with Apple isn't working on the iPad.
I don't have iPad, but I do have iPad Air and it works without the issue.
below is a screen from the apple review team
