ios - Is HealthKit query on WatchOS limited?

Question

The same code for fetching HKCorrelation (Blood Pressure) on iPhone returns all records, but on watch just 4. Is there a documentation explaining such behavior?

It looks like only records added after installing the app on watch are synced.

Answer 1

The issue was that on iPhone HKHealthStore returns all records, however on watch only records added by release versions of the app are fetched. That's why I didn't see the same data on watch as on iPhone.
