Alta HR stopped tracking sleep stages

[DenimNinja]

For the last few weeks, my Alta HR has stopped tracking my detailed sleep stages: deep sleep, REM sleep, and so on. It's only been tracking when I'm sleeping or restless. I've tried wearing my tracker one setting tighter, I've tried to reset my tracker, I tried setting it as a new device, and I even switched which arm it's on, but still no luck. What else can I do to fix this?

Realized I posted this in the wrong section. Any mods feel free to delete this as I can't seem to find a way to do it. I'm new to the forums.

I'm having the same issue.  Very frustrating.
