New vivosmart 5 - recorded sleep at first, now it's not?

My wife got a vivosmart 5 about a month ago. Her wrists are narrow so the vivo has a tough time picking up signal. Even so, it recorded her sleep the very first night. Once a week she'd get no data but we were happy to get any read considering the less-than-optimal fit.

For the last 5 days there's been no sleep score at all. I'm pretty sure the vivo app is updated

I'm new to Garmin's watches. Don't have any experience troubleshooting. Any help would be appreciated.

I guess I could try wearing the watch overnite?

Hello, Please make sure you have checked the following:

The watch must be worn at least two hours before bedtime.
The optical heart rate sensor must be enabled while sleeping.
A valid birth date must be saved in the User Settings in Garmin Connect (see Changing Device and User Settings in Garmin Connect).
To ensure the most accurate sleep data, make sure that your sleep and wake windows are set correctly (see Setting Sleep and Wake Window Times in Garmin Connect). If your sleep schedule changes, update your sleep time to ensure the most accurate sleep data.
If you have more than one watch, you must wear the one marked as your primary wearable device to bed.

Thanks for the reply. Newbie mistake. The Android phone got an update the same day as we checked for vivo5 updates. That made something go sideways. We reset the watch and sleep monitoring is now functional.
