No more sleep detected after firmware update to 22.22

Hey! 

Since the update to 22.22 my forerunner 255 doesn’t track any sleep and HRV data. Restart doesn’t help. 
Also body battery is not working, which I guess is caused by missing sleep data…

Anyone having the same trouble or any idea to solve it?

Thank you!!
