Apple released iOS 26.5 today with a HealthKit regression that prevents blood pressure permission requests from completing correctly. This affects only Inform clients receiving blood pressure data through the measurement endpoint via Apple Health.
Scope is narrow: only users who grant blood pressure permission for the first time on iOS 26.5 are affected. Users who authorized blood pressure access on iOS 26.4.2 or earlier are unaffected and will continue to see data. Bluetooth-collected blood pressure readings are not affected.
Workaround: Affected users can manually enable access via Settings > Privacy & Security > Health > [your app name], then toggle Blood Pressure on. Data flows normally once this is done.
Apple Developer Relations has confirmed this is a regression. We have filed a support incident and will update this page when a fix is available. The fix would need to be on the Apple side to be clear.
