The COMMUNITY MEMBER ONLY login was deactivated a while back. That was/is only for users WITHOUT tying the login to Verizon accounts. I had used that type of login for testing. When the last platform upgrade was done in Feb 2019, my default/account login failed for several weeks before finally getting resolved by the IT Department. Not sure what they did but they fixed my login/account somehow. Just keep calling in and opening tickets, having them escalate to the IT Team. And maybe start a new thread with your issue in the Forum.
