Mi band 6 cannot restore the reminder function.

Later, try to reopen the Bluetooth and Xiaomi Sports Connection Bracelet for firmware upgrade, or try to change a mobile phone for firmware upgrade. If the firmware upgrade fails after changing the phone or after repeated attempts, you can contact the after-sales staff to check the bracelet.
