Sleep and HRV not tracking

I have a pretty new Forerunner 265S and it's been working fine until 4 days ago when the sleep tracker and HRV tracker stopped working/only working partially.

- HRV is not being measured in the night or partially, resulting in incorrect results for my training readiness

- Sleept tacking is not being measured or starts way too late, resulting in incorrect results for my training readiness and sleep score

I saw this was a previous issue and wondered whether anyone had any solutions. I've tried all the obvious ones ie. switching on and off, checking the strap is on properly (nil changes), plugged it into my laptop etc.

It's really bugging me because it's offsetting other scores and then getting mad at me whenever I do a workout

Thanks in advance for any help!

Is the HR measuring at night throughout the period?

Hiya, yes Heart rate is tracking as far as I can see normally! So I don’t think there’s an issue with the sensor.

Hi. Reason I was asking is that I found once that the power save had got activated on the HR during sleep mode setting and that impacted HRV , sleep cycle reporting etc.

Try also to change the sleep schedule and then change it back to what you want as it may "trigger" something

Sometimes toggling the setting and then doing a soft reset seems to fix things

Soft reset - Hold in light button until the watch shuts down fully . Then Restart after say 20 secs.

Good luck!

Do you have a pending activity? A run or a walk where you pressed "resume later".
