@DTS Engineer Regarding Question 1: Yes, the application was installed exclusively through the App Store in both Step 1 and Step 4. The issue has been consistently reproducible on iOS 18.4 and 18.3.x devices following the outlined steps. Notably, the same steps did not reproduce the issue on an iOS 16.7.10 device, suggesting potential version-specific behavior. Regarding Question 2: While we do maintain an internal testing version of the app with a different Bundle ID (built from the same codebase), we specifically uninstalled the test variant, performed a full device reboot, and ensured only the App Store version was present during testing. Despite these precautions, the issue persists on iOS 18 environments. This indicates the problem is unlikely related to UUID conflicts from multiple installations, as documented in TN3179's "Build-time Considerations." We would be happy to provide additional diagnostics or clarify any details.
