I updated my watch last week to 5.2.1. Ever since my health app on the iPhone has not shown heart rate data since the update. The clock has collected the data and just not shown them in the health app.
I've restarted both devices. Paired the clock and restored from a backup. Paired the clock and setup as a new clock. Nothing.
What else can I try? Does anyone have this problem? My wife has the same clock, phone and update and has no problems.
