You’ll need a series 3 or later to use the new iphone unlock feature, because besides the iOS 14.5 update on the paired iphone you also need the watchOS 7.3 update on the apple watch. The AW series 2 stopped getting software updates last september, thus staying fixed on watchOS 6.is there a minimum apple watch/iphone requirement for this to work? i have a iPhone XS Max with a AW series 2 and i don't see the option. just updated to this beta. Was so excited for this feature. now kind of bummed out
