We found that setting the remoteHandle/callUpdate.localizedCallerName on CXCallUpdate will override the system contacts if a match is found, eg: CXHandle *callHandle = [[CXHandle alloc] initWithType:CXHandleTypePhoneNumber value:@"ContactNameHere"]; CXCallUpdate *callUpdate = [[CXCallUpdate alloc] init]; callUpdate.remoteHandle = callHandle; callUpdate.localizedCallerName = strLocalizedCallerName; Cheers, Ben

We have discovered this can be caused by not including a Deployment provisioning profile in your submitted build, or if the build doesn't run at all it also produces a Not Available for testing result. Apps will start in this state but should transition to available for testflighting after ~15 mins.
