activity from cloud
How do you get activity data from the cloud?
My old phone died (completely) and now I'm on a new iphone and struggling to get things from the cloud.
Apple Watch
Your activity would have been in the backup of your old phone that you should have restored to your new phone. When you unpaired the Apple Watch from the old phone, it should have synced a backup to the phone. Then you backup the old iPhone that you could use to restore content to the new iPhone.
