Hi,

We developed a app for iPhone and Apple Watch. The app has been tested and it worked well on iPhone SE and Apple Watch Series 6 running earlier OS. We recently upgraded the Apple Watches to Series 9 & watchOS 10.5, and the iOS on the same iPhone is upgraded to 17.4.1. The app can still be built on the iPhone but when I tried to install the app on the new Apple Watch, it won't work and shows "This app cannot be installed because its integrity could not be verified." To make sure it's not a OS issue, I also upgraded the watchOS on the old Apple Watch Series 6 to 10.5 and the app worked. I wonder what cause the app fail on the newer Apple Watch running the same watchOS.

Thank you

This error means your code signature is invalid. Is it possible that you haven’t added the new devices to your developer account? The fact that the same OS versions work on devices you’ve been developing on successfully for quite some time also points in this direction.
