My apple ID cannot be used to unlock my own watch
Recently I unpaired my iWatch and tried to pair my apple watch with the same iPhone. Since day one I was using the same Apple ID on iPhone and iWatch but I am getting an error "The Apple ID "" cannot be used to unlock this Apple Watch."
My apple watching is missing from the iCloud but I can see it under the support section.
I am the real/first owner of this apple watch. I would like to know how to solve this issue.
Apple Watch Series 3, watchOS 7
