pairing Apple Watch Series 5 with an iPhone 7
The latest user guide says that you need an iPhone 8 and iOS 16 to pair with any Apple Watch. Obviously, since the Apple Watch Series 5 and iPhone 7 were issued before iOS 16, there must be a way to pair the two. How can I reach the older user guide to pair the older iPhone 7 with the older Apple Watch Series 5?
