Hello !
I know nothing about apple watches since I never got one until I offered a Garmin to my bf and he gave me his old Apple Watch.
I cleared the watch and tried to pair it with my phone but it asks me to update my phone to IOS 26 ?
I don’t want that update and I saw that this watch is supposed to work with at least iOS 17 and I have iOS 18 ://
Is someone willing to help me? Thanks !!
