Why the Xiaomi Smart Band 8 cannot be connected to the phone when log into the same Xiaomi account?

There are the following reasons:
1. The current phone cannot connect back, the old phone has unbound the device, and the new phone has not synchronized the account, so it cannot connect back to this device;
2. Confirm which interface the content displayed on the band screen is on. If it is on the QR code interface or language selection interface, unbind the device from the Mi Fitness APP on your phone and scan and pair again;
3. Confirm whether the Bluetooth icon on the band is always on. If it is, use "Find Phone" to confirm whether it is connected to the current phone. If it is not, unbind the device on the app and use the current phone to rebind the bracelet.
4. If the device is not available on the device management page of the old mobile sports and health app, it indicates that the old phone has unbound the device. After the new phone logs in to the same account and synchronizes, the band will not be displayed. If the band is on the QR code interface or language selection interface, scan and pair again;
5. Connect two phones with the same Xiaomi account in the app to a band. After restoring the band to its factory settings, use a new phone to pair again and turn off the old phone's Bluetooth. If the new phone cannot connect back, it could be because the new phone did not automatically retrieve the new login and pairing information.
Suggestion:
1. Please try to avoid logging into multiple phones with one account as much as possible;
2. If there is already a situation where you cannot connect back, please turn off the Bluetooth function of other devices that have already logged in to the account and try again;
3. Please keep the network in good condition, remove the app and reopen it. Trigger the cloud to resend login and pairing information to ensure that the band can be reconnected.
