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.
When was community only ID login deactivated? I'm still using mine. When we switched from Jive to Lithium again this year, I had to reset my password and I have been using my community only ID login since.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
