Blocks of heart rate data missing on the iPhone X
I have an iPhone X and Apple Watch 5, both updated with the latest iOS 14.0.1 and Watch OS 7.0.
In the last week, and just before the latest OS upgrades, I noticed that blocks of heart data were missing and my walking map is not shown in the Apple Fitness app on the iPhone. My iPhone AutoSleep is affected by the lack of data.
But the heart rate data is all visible on the screen of my Apple Watch, even the data that is missing on my iPhone X. Never before did I have a problem with missing heart rate data. What's up?
