Nikhil Gupta: Hi Nikhil, Can you please go to Bevel -> Profile -> Customization -> Calculation, screenshot the view for me?

Also, is this the first time that you are using an Apple Watch?

Randell please find attached screenshot. And no, I am not using apple watch for the first time. The data was coming in just fine until today.

Nikhil Gupta: Got it, it seems like you are using Bevel' default calculation method. Let's go ahead and verify the data in Apple Health.

Can you please go to the following for me and send a screenshot?

1, Go to Apple Health -> HRV -> Scroll down to the bottom, tap "Show all data" -> Tap on today's log which is Jun 20th -> Screenshot a good chunk of your HRV data that FALLS WITHIN your SLEEP PERIOD.

Also, just to confirm- your watch wasn't on low-power mode or has low battery last night, correct?

Randell this is HRV. No data after 11:10 pm last night. My watch is was not on low power mode though

Nikhil Gupta: on 20th, were you able to check as well? or just during your Entire Sleep period, did your watch log HR/HRV data?

This is Heart rate data. Available only from this morning. Looks like both HRV and HR are not there for last night

Randell there is no data for hrv during sleep on 20th

Nikhil Gupta: That is weird, the only reason I can think of why your watch did not record your overnight vitals are

Actually, we can verify this. Can you please go to your Apple Watch -> Settings -> Battery -> You should be able to see a graph in there of your AW battery level, can you screenshot that for me?

Randell not able to take a screenshot, but this is how it looks like. I may have put it on charge and may not unlocked the watch while wearing again at night. It is usually on focus/dnd mode during this time. Could that be an issue?

Nikhil Gupta: Hm I am not sure. any chance that your Apple Watch did an OS update last night? Also, try to restart your watch and see if it happens again tonight.

Nikhil Gupta: Are you still experiencing this issue as of today?
