Problem pairing Apple Watch Series 5 with iPhone 6s with iOS 15.7.2
According to the compatibility reports, the Series 5 watch should be able to pair with the iPhone 6s. My kids have identical iPhone 6s. I bought them Series 5 watches for Christmas. My daughter's phone had no problem pairing. My son's will not pair. It keeps saying that the watch requires an updated iPhone. The phone has the same iOS as his sister's. I've reset the watch back to factory, rebooted both the phone and the watch. What gives?
