Firmware 20.26 sleep (mis) detection

Can you make sure you're meeting the requirements (especially the 4th requirement) listed in My Sleep Statistics Are Not Displaying in Garmin Connect?

That's not entirely true though, you can have battery saver activated during sleep (I do) as long as you exclude the optical heart rate in it...

I have the same issue on my Forerunner 955.

Never had issue recording my sleep session at night before and now it's been missing two night in a row, just after I installed the 20.26 update.

I haven't changed any settings, nor sleep pattern. No energy saving option is on and my HR is still recorded correctly during the night, just the sleep that isn't detected.

I tried restarting the watch and stuff but still nothing. I really suspect the update to have an effect.

Warraa- May I have permission to take a look into your Connect account and reach you via email if necessary? 

Yeah I don't mind

I'm not sure if any of your settings happened to have changed, but can you double check your sleep window to make sure you have valid sleep/wake times? Setting Sleep and Wake Window Times in Garmin Connect

I have exactly the same issue and it also started two days ago. FR965 on 20.26 firmware. Sleep window set correctly,  battery saver off, I didn't change any settings after firmware update. Still no sleep data gathered for last two nights. 

Same issue here when updated to 20.26. I have noticed that FW updates usually require a restart so I did that today. We will see if it is fixed tonight. I wish Garmin just forced a restart after all FW updates.

So it's been working again for the last two nights for me (after being broken for 2 nights after 20.26 update) and what I did was doing a restart of the watch and changing the sleep window closer to my actual sleep (even if this setting never really did matter until now for me).

Not sure which one of the two made it work again but there was definitely something with the 20.26 update that messed up the sleep function.
