1. What should I do if I don’t see the sleep data of the night on the APP?

1. The mobile APP has just been opened, and the health data has not been uploaded yet. Keep the connection status between the bracelet and the APP, refresh it several times and wait for 3 minutes to check it.
2. The premise of sleep data is that the watch must be worn correctly all the time while sleeping at night. If the watch is not worn or the watch is not worn against the skin, data will be lost, and sleep monitoring will not be turned on due to missing the sleep judgment period. . There is no sleep data displayed on the APP.
