1.Remove → re-add each friend whose data doesn’t update
Tried before, not work, the data will be updated at that moment, then, stop again.
2.Ask the friend to check Fitness Sharing / Motion & Fitness switches
Check, the setting is fine.
3.Turn OFF/ON Fitness Tracking and reboot
Tried, not work, nothing heppened.
4.Sign out/in of iCloud
Tried before, it doesn't work. I tried many times.
It will lose my data in wallet and I need to add my card again, it is a little bit annoyed.
5.If still broken → unpair/repair Apple Watch
The reason that I don't want to use this is that there will be two same devices in the data bank list, like two Apple watch Ultra 3.
I have to admit that I do not like to see that, especially I do not really change my apple watch.
It makes me uncomfortable.
I really think this issue is coming from the server, not in local device.
Perhaps it will be fine someday just like the last time I had.
I am really appreciate your time to help me, thank you.
