AutoSleep. 
Health Check. 

Problem 9. 

Either you have not been wearing your Apple Watch, or there is a problem with health data not being sent from your Watch to your iPhone, or AutoSleep does not have permission to read your health data. 

If you genuinely haven't been wearing the Watch, just put the Watch on making sure that you have entered your passcode. The error will go away once the Watch has collected data for 5% of the day. 

Otherwise, first check the following: 

Common Reasons for No Data Synch

1. Is bluetooth turned on? Some people accidentally turn it off. It’s easy to do. 

2. Are either of the devices in flight mode?

3. Did the Watch go into low power mode (< 10% battery)? 

4. Do you have a passcode on your Watch and have you entered it? This is required for background heart rate data. 

5. In Passcode in the Apple Watch settings app have you turned on Wrist Detection? This is required for background heart rate. 

6. In Privacy in the Apple Watch settings app, both Heart Rate & Fitness Tracking need to be turned on. 

7. Do you have a prominent wrist tattoo?



If all the above are ok then: 

This is sometimes due to the iOS / WatchOS update not correctly starting Apple Health services.

If that doesn’t resolve it, then either you did not grant permission for AutoSleep to read your health data, or this is due to a bug that was in the iOS update process that removes health permissions for apps. It doesn’t affect everyone, but does happen from time to time. 

Here’s how to fix it.
