Suddenly no REM sleep recording?

Anyone having issues with their Garmin suddenly not registering REM sleep? As of 1/17, I suddenly am not recording any REM at all. This has never happened to me before. I need to watch my sleep quality due to a seizure disorder, so need to know if this is an actual issue with my sleep or if this something that has changed with the way things are reported?

VA4 works fine here. I get 4-5 hours of REM per night.

Works fine for me - well as good as it gets on a Vivoactive which isn’t that great.

This is happening me since last week too. A few nights no REM recorded at all, and I slept well last night. It worked after charging but is back to its old tricks today.

Just forget about sleep-recording on an smartwatch. Its not possible.

Be happy if the watch detects the right time you get to sleep and wake up.

You need way more sensors then an optical HR and gyro. There is no way to detect sleepphases without electroencephalography.

Yes! Mine also stopped recording REM (I remember dreaming, lol!) about 3 weeks ago….

Mine worked fine for two weeks but for two nights now it recorded zero REM sleep. I remember my dreams. Is this a known foible of this model?

Actually the Apple Watch 6 and up are really good at this. Watch "The quantified scientist" on YouTube...

I think it’s too much movement while sleeping? Mine stopped doing REM too.
