A. Ensure that the sleep tracking feature is enabled in the app settings. Go to the app, navigate to 'Settings', and check if sleep tracking is turned on. If it is, try recalibrating the sleep settings by turning it off and then back on. Additionally, ensure that your watch is worn snugly on your wrist during sleep to improve accuracy.

B. Try updating the app to the latest version, as updates often include bug fixes and improvements. Go to the Google Play Store, search for Fitdock, and check if an update is available. If so, install it and see if the sleep tracking improves.
