I use adhoc distribution to install my app to iOS and (via Apple Watch app) watchOS. After updating to watchOS8 and iOS15 the app did not start on the watch. iOS app is running without problems. I tried uninstalling an re-installing the app on the watch. Installing throws error: "This app could not be installed at this time. Could not install at this time." Tried re-installing the app on iOS, switching deployment target in XCode to ios15 and watchOS8, rebooted all devices. No success. WatchOS App is running in Simulator without problems and debugging the app on the watch via XCode is working fine, too. Only adhoc distributed installation fails. Console shows no specific errors on both devices. Adhoc distribution UUID's are correct. Do you have any suggestions?
