I did what everyone said to do with the Watch. I unpaired it, and then backed up the phone with an encrypted backup. I restored my backup on my 7 plus and then re-paired my Apple Watch. At first it wasn't registering any activity, no stand hours, no exercise, the only was calories from the iPhone and then I rebooted my Watch and got a prompt to set up the Activity feature and then it started registering. But I went onto the Activity app on my 7 plus and noticed all my Activity data was gone from when I got my Watch at launch last year to yesterday. I did an encrypted backup, I don't understand why it didn't save over. If I unpair my Watch from my 7 plus and repair to my 6 plus, will it gather the data from my 6 plus and bring it over if I repair to my 7 plus again?
