Please be sure you are wearing your watch continuously to get a fitness reading, as there are a number of factors that may prevent the necessary data from being transmitted:
- Be sure your Gen 2 Wellness watch app has all the relevant permissions for the sensors. Visit Settings > Apps & Notifications > App info > System Apps > Wellness > Permissions > Sensors
- Allow for up to a week for the software to gather historical heart rate data and calculate your Cardio Fitness level (estimated VO2 max).
