Dear fellow devs, I'd be helpful for hints concerning the following problem:
My MacOS/iOS app exports generated audio data as wav files using the SwiftUI ".fileExporter" view modifier. Everything works perfectly fine on all test devices, my own as well as those of TestFlight users. Also the iOS version of the app available in the iOS App Store works fine. The Apple reviewer of the MacOS version however complains that the "Export button" which should trigger the file export doesn't react. I have no idea why this problem should occur in their tests as neither me nor my beta testers can reproduce it.
In lack of any other ideas I guessed it might be related to the document types registered by the app and added the entry below to the plist, but the reviewer still reports the same problem. Any hints would be very welcome.
