Fenix 7 Heart Rate Randomly Stops Recording

Wondering if anyone else has had this problem.

I’m on 9.33 and have not set up or enabled battery saver mode

Got my f7 sapphire solar 4-5 days ago. It worked great up until 2 nights ago. I noticed it didn’t auto detect sleep. It looks like it randomly stopped recording HR around 7 pm and didn’t restart recording until I restarted the device in the morning. (When I noticed sleep wasn’t detected).

It stopped recording again yesterday evening after a run. I checked the setting and the wrist heart rate setting was still set to auto. I toggled it off and back on and it began recording again.

This morning I checked to see if it recorded my sleep and saw the same issue. HR stopped recording around 10 pm and started recording again around 4 am. It also stopped recording any data for around an hour late this morning at work so I don’t believe it’s related to my “sleep time” I had entered. 

Has anyone experienced a similar issue?

Im working with Garmin Support but they don’t seem to know what’s causing the issue.
