Heart rate missing data

Since OS 14 and subsequent big fix, the heart rate collection is missing large chunks of time day and night. I have not changed how I wear the watch. My health app and SleepWatch app are affected bc if it.

Apple Watch Series 3, watchOS 5

This is a terrible solution offered by Apple. I track my heart rate because of heart issues, and the fact that 3 years of monthly data it is now missing from my watch is flat out unacceptable. Apple should correct this with a software update, not ask me to wipe my phone. I believe the data is still on the phone; I can see it - it's just now showing. Also, I cannot wipe my phone - Apple maybe doesn't know this, but there's this thing called COVID-19, and my phone has a soft RSA token app so I can log on and work each day. The only way to reactive it after a wipe is to go into one of our corporate offices, which is not allowed accept for an emergency, and Apple screwing up my phone's data is not an emergency. Other issues, volume decibel data is gone, GPS is not tracking when I run or walk outdoors. Unacceptable, Apple!

I recently upgraded my iPhone 11 Pro to iOS 14 when it came out in September. Then I bought a new Watch series 6 and upgraded it to watchOS 7 the first week of October. Now I find out that Apple has permanently deleted 3.5 months of this year's daily distance walked/ran and all workout GPS routes history! And 2 months of heart rate data is completely missing.


Their solution is unpair my new watch, erase my phone and restore from backup but the backup has the same problem since it backs up daily and I discovered this days after it happened. They have a whole support page dedicated to this problem to "prevent FUTURE data loss." If it's too late to recover it, oh well it's permanently gone. https://support.apple.com/en-us/HT211865


I can't believe more people aren't having this problem! SOOOOO disappointed in losing hard-earned data! 2020 *****!

I had this problem and chose not to go through the wipe and restore as I was about to upgrade to an iPhone 12.

I just got the new phone and restored from an iCloud back-up of my old phone.

All my health data is available again on my new iPhone...

So, I would recommend you back-up your phone to iCloud, wipe it then restore from the iCloud back-up... I think all your 'lost' data will return. The wipe an restore is not as painful as you might think.

My theory is that this is not a data loss issue but a bug that just stops the data from displaying.
