Why is there no response when tapping "open on phone" on the Xiaomi Smart Band 8?

If there is no response when you tap "open on phone" on your band, please check the following reasons:
1. Check whether Mi Fitness APP is running in the background of your phone. Please turn on the APP background protection;
2. Check if your phone is currently in lock screen status. If the phone is locked, the phone can not jump to the APP page;
3. Currently, the function is trying to adapt to more Android models. Please wait patiently;
4. iOS phones do not support this feature.
