Hi I’ve just bought a series 3 Apple Watch. I have unpair my series 2, which gave me an error ‘unpairing unsuccessful’ on my iPhone. When I’ve gone to setup my new watch, the last backup available to select is April 2017. The series 2 Watch appears to have been wiped as it’s now back at the pairing screen. How do I get today’s backup to setup the new Watch? Many thanks M.
