When multiple phones are logged into the same Xiaomi Account, you can not reconnect to your current phone or the Mi Fitness APP can not show the Xiaomi Smart Band 9 Pro.
Here are several reasons for this issue:
1. The current phone cannot reconnect because the old phone has unbound the Xiaomi Smart Band 9 Pro and the new phone has not synchronized the account. Therefore it cannot reconnect to this device;
2. Check what the band is displaying. If it's on the QR code screen or language selection screen, unbind the device from the Mi Fitness APP on your phone and then re-scan to pair;
3. Make sure the Bluetooth icon on the band is constantly on. If it is, use the Find my phone feature to check if it's connected to the current phone. If not, unbind the device from the APP and then rebind it with the current phone;
4. If the device is not shown on the old phone's Mi Fitness APP device page, it means the old phone has unbound the device. After logging in with the same account on the new phone and syncing, the band will not be displayed. If the band is on the QR code screen or language selection screen, re-scan to pair;
5. When connecting the band to two phones using the same Xiaomi Account, after resetting the band, pair it again with the new phone and turn off Bluetooth on the old phone. If the new phone still cannot reconnect, this could be because the new phone hasn't automatically retrieved the updated login and pairing information.
To avoid this issue, here are some suggestions as follows:
1. Try to avoid logging in with the same account on multiple phones;
2. If there is already a situation where you cannot connect back, turn off Bluetooth on other devices logged in with the same account and then try again;
3. Ensure a stable network connection and restart the APP after removing it to trigger the re-delivery of login and pairing information from the cloud, ensuring the band can reconnect.
