I have deleted an email address recently because of unwanted spam but keep getting password requests as below. I have several email BT accounts and don't want to jeopardise them in the process. When I enter my password (as I remember it) I get the 2nd message. Probably because the email address doesn't exist anymore. Can I not just clear it all?
Its a problem with your device/app not BT. You haven't deleted the account fully and the device is still trying to connect to it.
If you have deleted the email account why are you trying to log into it?
