Firmware 20.26 sleep (mis) detection

Same for me actually. Before, I didn’t really have a window set, I set the window to one minute overnight and just manually activated sleep mode when I went to bed, it always tracked it accurately. My sleep varies wildly so I preferred handling it this way. I may try going back to it. But I am still trying to get 3 weeks of tracking for my HRV baseline so I will probably wait before I experiment with that.

Same here. I slightly changed sleep window and restarted the watch and it detected sleep this night. 

I restarted the watch yesterday and have all sleep metrics today. SMH, how hard is it to just auto restart after FW update.

Same fore me. Restarted watch multiple times, nothing helped. 2 nights no sleep detected, 1 night it detected and again 2 night nothing. I didnt changed any setings and it started mising sleep detection after updated to 20.26.... before last update worked every single night.....

For me after upgrade to 20.26 it does not detect correctly when my sleep ends. It detects that sleep ended about 1-2 hours earlier than I actually woken up. And in such cases it does not display the morning report.

On previous firmware it worked correctly.

Also noticed when sleep detection is missing, there is also missing night HRV... 

I see continuous HR during sleep.

Before update to 20.26 sleep detection worked perfectly.

On above graph you can see that the watch detected wake-up around 7:16, and later it detected a subsequent nap. I actually woke up after this nap.

Here similar situation:

Yesterday morning I updated to version 20.29 and the problem is still there.

Continual heart rate is there without any gaps. HRV is missing again, sleep data is missing again.

1. Yes, without any gaps

2. Yes

3. Yes you have permission to view my Connect acount.

4. Yes

I am having the same issue since upgrading to 20.29 - no sleep detected and no HRV.
