My S60 stopped recording sleep data 3 days ago. Anyone else seeing the same problem?

Yes same here. I'm guessing the last update to the garmin connect app is causing some issues. Hopefully it's fixed soon

try checking that it is set as your primary device for health tracking

Did you manage to resolve this? I have the same problem for a few days now and there was no update on my watch. Also seems like the calendar isn't syncing either, which is odd.   

Mine starting working after I removed it from the app and added it again. I would first try removing the Bluetooth connection from your phone first and then paring the device with your phone once again. If that does not fix the problem then remove it from the app, delete the Bluetooth connection and add the device to the app again. I did go straight to removing the device from the app but that forced me to re initialize all my options again. I think the part that fixes the problem is the e doin the Bluetooth connection. 

Yes if I remember correctly I had to remove all the garmin apps from my phone and also do a factory reset on the watch. Then I followed the setup as if I had a new watch. 

Yes - Sleep is not transferring to my iPhone11 (didn't have a problem with the 8S) but if I connect to my windows PC and sync when I next connect to the phone and sync all sleep returns.

But now I have an additional issue yesterday I walked 12.59Km playing golf and when finished my step count for the days showed 16500steps Today when I synced my golf was recorded but my golf steps are now where to be found. I'll try all the resets below.
