iphone 13 is stuck on the activating screen
So I just tried to set up my iphone 13 pro from my iphone 7.. seemed easy enough, put the phones next to each other, follow the few steps and wait. And then I waited 90 minutes, only for my old phone to tell me the set up had failed.. but the new phone still has the thinking circle of death moving and says that its activating the device. I turned my old phone completely off, thinking it might cause the new one to stop "thinking" but to no avail. I also can't power off the new phone... it's just stuck and I don't know what to do. Help?
