Why is there no sleep data when swiping to the sleep widget of the Xiaomi Smart Band 9 Active after waking up?

The absence of sleep data on the sleep widget is explained by the following reasons:
1. When you use the Sleep APP during the night, the band monitors your sleep and tracks various sleep stages. Upon waking up, the band not only recognizes that you're awake but also records your wake-up time. However, if you swipe to the sleep widget immediately after waking up, the band has not fully processed the data yet;
2. The sleep widget registers accidental touches when you move or swipe during the night, even before you fully wake up. To prevent such accidental interactions from affecting the data, the band delays updating the sleep data until the algorithm has fully detected that you are awake and no longer in a sleep state;
3. If you swipe to the sleep widget immediately after waking, the data is not fully refreshed, as the algorithm is still processing your wake-up time and sleep stages. This results in a temporary mismatch between the sleep data displayed on the widget and your actual sleep cycle.
