Hi! I have some questions regarding Apple Watch for family members: Is there any limit to how many Apple Watches can be paired to a single iPhone? Do Apple Watch apps have access to a unique identifier to distinguish which Apple Watch it is running on? Are any HealthKit metrics not available on a family member paired Apple Watch? For example, falls. Are family member HealthKit metrics programmatically accessible from the parent phone? After setup, is there any reason that a family setup Apple Watch would need to once again come into contact with the parent phone? Can family setup Apple Watch watch faces, settings, and app updates be facilitated remotely? For example, if I have a grandparent in a different country, can I control settings, etc., while in the US?
