I believe this is an important part of the system, as all the calculation and analysis depends on the sleep data. Please fix it ASAP, it makes our devises futile.

1. Yes, I meet all the sleep requirements.

2. Yes, started with 20.29. I've had two days of "no sleep detected" even though it has all the HR and other necessary data.

3. It has happened twice to me. 8 hours for both. 

4. Yes. Look at September 30th and October 15th.

Hello. My Forerunner 955 which I got on december 29 2023, stopped recording sleep and hrv 2 days ago. On Saturday, October 19th, I slept around 11 hours none of which got recorded. Similarly last night, and I'm concerned it'll happen again tonight. I am on version 20.33. Battery saver is not enabled. I consider this error to be a factory malfunction and am strongly considering making use of my warranty. Please help me fix this asap.

1. It is an intermittent issue for me. Sleep tracking works most nights, but randomly fails.

2. I'm not entirely sure when it began. I have had my watch for more than two years, but only had problems with sleep tracking since sometime in the last six months or so.

3. I think most issues have been on nights of 8 hours or more, but I can't really recall as I have had this issue for a while without taking notes.

4. yes

5. yes

I recently started wondering if this bug is somehow related to the missing elevation and temperature data for activities, as both issues seemed to start at approximately the same time. If it weren't for the fact that many others seem to have this issue I would have thought that my 955 was dying on me.
