It’s happened a few times now with FR 965 FW16.17
I wake up in the morning and the watch hasn’t registered sleep, HRV or Body Battery updates all night. I get an error message that indicates that the watch didn’t think I was wearing it last night. However- I do have HR data all night.
So- the watch IS measuring HR all night. But, isn’t updating the other functions. Went to bed at my normal time. Got a good night’s sleep.
Interestingly- I noticed that the body battery had just been on a slow decline since the prior day. Even through an afternoon activity (run), where all data appeared to be collected.
a reboot gets things going again, and my BB which had declined to the single digits, jumps immediately back up to 42. Then everything seems fine again. ???
This happen to anyone else? If so, it should be a bug report. If not- then maybe I have a hardware issue?
