Why can't I find the Amazfit PowerBuds in the app after logging in with another mobile phone?

If you log in your Amazfit account with another mobile phone, you have to bind the earphones again.
If you unbind or ignore the Amazfit PowerBuds in the Bluetooth device list on your mobile phone, the Amazfit PowerBuds in the app device list will also be unbound. If you need to add them again, please repeat the binding process.
