I recently updated both the watch and the iPhone to the latest software. When I try to add a friend to Activity it says “Update required. To share activity with (friend), first update iPhone and Watch to the latest iOS and Watch OS. "I went into the settings on each one and it says" your software is up to date "
I tried logging out and back to iCloud and also difficult resetting both my phone and my watch.
Watch is a series 3 and I have an iPhone 8 if it matters.
Any insight will be appreciated !!
