Was struggling for hours before discovering this thread. The issue for me was for literally any app i tried to upload, not just one specific app. I did discover a workaround. WORKAROUND: Go to Certificates, Identifiers & Profiles Create a profile that specifically targets your app bundle identifier create the profile, download it disable automatic profile management in xcode under Signing & Capabilities Import newly downloaded profile worked for me :)

I see that another developer has also run into this issue: https://developer.apple.com/forums/thread/791352?answerId=847563022#847563022 The suggested fix of quitting the Settings app before configuring the app did not work for me. I've submitted a bug report: FB20479096

I am testing on iOS 26. I have reproduced the bug and collected a sysdiagnose (thank you for your guidance). I have uploaded the sysdiagnose to my bug report, so if you could get my ticket back in the loop I'd appreciate it. Thanks!

Any update on this? When can we expect the next version of the sample project?

@anton_kliukin It stopped happening to me after I updated to the newest beta (it was 26.1 beta 5 at the time I believe). Unfortunately there has been no update on my bug report, so if this is still happening for you, I don't know if there's anything you can do except submitting your own bug report.
