No heart rate being tracked during sleep

It used go work spot on. Nothing has changed.

I took off my watch one night to let charge on its stand and fell asleep so i expected the sleep app not to track hearttate. Since then i have worn my watch to sleep but heartrate recording has not resumed. Help?

Thank you

Hi @Stanton_Young, the app always shows all data it has. If the HR is missing, the app cannot read the data from the sensors. What wearable do you have? Is Body sensors permission granted on both phone Sleep and the companion app on the watch?
