It appears to still be an issue in IOS 14.6 and Xcode 12.5.1

I am seeing this today as well

I'm having issues with this today - similar situation (no reason for the behaviour to pop up, and no idea what is going on)

Me today as well...

I have submitted a bug report and an email to Rich. Hopefully he is still the guy to go to!

Rich Kubota at Apple said they are investigating the issue

Update - the issue is resolved for me. The IAP works now. I had also upgraded my phone from 15.0.x to 15.1.x right when it started working so maybe that's a coincidence and maybe it helped.

I am seeing this on real devices using iOS 17.3 and XCode 15.2. Happens on iPhone XR. Seems to only happen when attached to XCode debugger. Note I am NOT using navigation in this app. My AVPlayers are in a scrollview. I get multiple error messages, including: [MADService] Client XPC connection invalidated Visual isTranslatable: NO; reason: observation failure: noObservations Error processing request from MAD on result: Error Domain=NSOSStatusErrorDomain Code=-128 "VCPMADServiceImageProcessingTask canceled" UserInfo={NSLocalizedDescription=VCPMADServiceImageProcessingTask canceled} request: <VKCImageAnalyzerRequest: 0x281f7c960> requestID: 13 madRequestID: 13 cancelled: YES
