21.20 strange stress level and sleep time being inaccurate

I have noticed the same here with my FR255 after the 21.20 version (my girlfriend too). My stress levels peak every time, even when I’m sleeping or relaxed in the sofa. My heart beats also peak when I’m walking to 145bpm (extremely strange).

I hope they fix this asap

Thank you for sharing. Can you both please check the following? 

1. On your watch, long hold the middle left button and scroll down to User Profile > Heart Rate & Power Zones > Heart Rate. Does your Max. HR look realistic? If not, please adjust it and test it out for a few days. 
2. Does your heart rate data seem accurate outside of activities? 
3. Can you make sure the HR sensor on the back of the watch is clean?
4. Make sure to check the fit of the watch. It should be snug, but not too tight. 

May I have permission to view your Connect account and reach you via email if necessary? 

I have checked everything and it looks fine to me. If you could view my Connect it would be great  

Hi, thank you for reaching out. Last couple night were fine considering sleep time duration, stress levels still a bit odd and high, but I have to add that I may wake up, click daily report, go to bathroom, get back to bed, have more sleep like 1-2h and 965 doesn’t consider it as a nap/sleep (even if I switch my watch back to sleep mode). 
yes please, you have my permission to view my Connect and reach me via email, thanks.
