I setup an Apple Watch SE for my son using my phone. He doesn't have a phone, just the watch. Now, I want to access all his activity/workout data for the past 30 days as he needs to document it for some school activity. I tried to get access to the data from the Watch app on my phone, but it's not working. It says permission needed on the watch, which I grant every time but data doesn't show up. How can I go about getting this data from his watch? I didn't find anything on icloud.com when I logged in using his credentials. I have confirmed that the iPhone & watch are all on the latest version of the OS.
