A. Ensure that the watch is worn snugly on your wrist, as a loose fit can lead to inaccurate readings. Additionally, try to keep the watch clean and free from any obstructions that might interfere with the sensors. You can also try resetting the watch to recalibrate the sensors.

B. Check if there are any updates available for the watch or app that might improve the sleep tracking feature. Sometimes, software updates include improvements to tracking algorithms.
