Was there an update to add naps to Vivoactiv 4
No.
Not gonna' happen. They force customers to buy new stuff.
Hello,
There are only a few watches that currently support Nap detection. You can find the compatible watches here: Frequently Asked Questions About Tracking Naps
The Vivoactive 4 is not expected to get this feature. However, if you are interested and would like to submit this suggestion, you may do so here: Garmin Ideas Portal
Thanks I was confused because must have been a glitch as nap of 2hours showed up on my watch but just once, nit bothered about naps just confused
