How do I read partial field availability on the support page?

On the wearable-data support page, a partial-support indicator means data may arrive from that device but not all fields will be populated.

On the wearable-data support page, a partial-support indicator means data may arrive from that device but not all fields will be populated. This reflects both device hardware and what the provider's API exposes for that model.

Availability is device- and provider-specific. For example, some HRV/VO2 max metrics depend on hardware generation, and certain fields like Polar resting HR via the Body event are not currently delivered.

Check per-field and per-device support rather than assuming full coverage.
