Apple Watch 7 and iPhone 6s iOS 15.7.2 not pairing
Hello, I have an Apple Watch 7 and an iPhone 6s iOS 15.7.2
When I try to pair I get an error message.
I have tried automatic and get an error "iPhone Out of Date. This apple watch requires a newer version of iOS".
When I try manually. I enter the 6 digit code, it spins for a bit then says unable (there is an error message that pops up too quickly to read).
Help!
All apple literature says these are compatible.
:(
