Tried that on the android device, and it comes up with another code instead of 370648 and still gets stuck.
The worst part is, it makes all my trusted device installation unable to unsync. This computer has avast installed with password in it. But I couldn't unsync the password account to reconnect to another. It simply, as I said, stuck. I tried uninstalling avast, clean uninstalled using the avast tool and still the password part get's stuck to the account. It won't let me change account.
I hate to ask but can you just nuke all the associated devices for password on the account and reset it? I already saved and export the list of passwords. If I can't add new devices to sync or remove any devices, or even switch accounts. I simply have to just uninstall and not use Avast, because going forward for me it will steady becomes unsecured as I switch devices and computers in the future.
