Same issue here, but we're getting this error only for our app extension Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.RTMSkO/extracted/Payload/AppName.app/PlugIns/AppName Share.appex : 0xe8008001 (An unknown error has occurred.) Verify that the Developer App certificate for your account is trusted on your device. Open Settings on the device and navigate to General -> VPN & Device Management, then select your Developer App certificate to trust it. Just rebuilding the app works to alleviate the issue, however the next time running will give the error again. So every other run it happens. Oh and no developer app certificate is available at the suggested location in the error.

Same issue here, with our CarPlay navigation app that crashes with the 15% CPU over 60 seconds message when put into the background. Also a symptom that we see (don't know if that is also the case for you guys) is that the app gets suspended for a longer time (between 30 secs and 30 minutes or so). That makes the app unusable in the background. We are not sure if that last one is related, but seems to occur from iOS 15.2.1 and iOS 15.3

In our extensive bug report about this issue (beacon monitoring specifically) the status has been updated to 'Potential fix identified - For a future OS update'.

Same issue here. Very inconsistent behaviour, which we also hear from our users. Our app starts in the background when it enters our Bluetooth beacon region and starts scanning. When the iPhone is right next to the device, it still finds zero peripherals sometimes. Our users also give this feedback, where on iOS 14 versions it worked near-100% of the time, where now it is very inconsistent. So concretely, it doesn't call didDiscover peripheral after using scanForPeripherals. We give the service identifier of the device to the init of the CBCentralManager via the CBCentralManagerOptionRestoreIdentifierKey and also use that identifier as a parameter withServices for the scanForPeripherals method. I've reproduced this locally a couple of times on iOS 15.1, where the scanning doesn't return anything for more than 20 seconds. Then, a couple of seconds after that, we get a trigger again didEnterRegion and start scanning, which finds the same device within a couple of seconds.
