I keep trying to share data with my friend I accept her invite then it shows up with 0% constantly. Then the next day she disappears off my fitness app altogether. I have tried unpairing my watch, deleting and re adding, signing out of iCloud and restarting my phone
Apple Watch Series 3, watchOS 8
According to:
Share your Activity with your iPhone and Apple Watch - Apple Support
To share Activity, you and your friend both need an iPhone. You get notifications about your friend's progress when they close their rings, finish workouts, or earn achievements.
As long as your iPhone can connect to the Internet and you're signed in to iCloud, you can get updates about your friend's activity each day. If your iPhone can't connect for multiple days or you sign out of iCloud, you might see missing days.
If you still need help, contact Apple Support.
