Why does the Xiaomi Smart Band 8 not generate exercise data after exercising?

To issue this problem, please refer to the following information:
1. Make sure the band is fully charged during exercise. If the band is turned off or restarted during exercise, no exercise data will be generated;
2. If outdoor exercise is enabled on the Mi Fitness APP side, please make sure the APP is running in the background and remains connected to the band. If the APP is disconnected from the band or the APP is blocked, the exercise on the band will be forced to exit and no exercise data will be generated;
3. Exercises initiated from the APP will not synchronize exercise reports to the band. Exercises initiated from the band can only be viewed on the band. So if you need to view exercise records on the band, please initiate the exercise from the band;
4. Outdoor exercise requires the mobile phone’s GPS to record the track and exercise distance. Therefore, when doing outdoor exercise, the mobile phone needs to turn on GPS and APP location permissions.
