Garmin Venu 3 not recording naps

Hi, I've had the Venu 3 for about a week. I've taken two naps with it but they were not recorded by the sleep tracker. I've read that I can manually track naps but I'd like them to be automatically recorded.

Is there any way to auto-record naps?

Thinking about returning the Venu 3 if it doesn't accurately record naps.

Thanks!
