Product Engineering Team Meetup Won't Let Me Register

God only knows why this has to go through MS Teams. I consider MS one of the least competent online companys. Yes, I have a Microsoft Live login but it has NEVER worked properly to login to any clients Teams meetings. My MS Live login script saved on Chrome is never recognized as legit my the Microsoft. I have to get in via an invite from the sponsor.

I would like to Register but between your cute "Something went wrong..." message and MS Live not recognizing my PepperCADD Windows license login I'm not going to attend unless you guys fix it. Let me know when I'll be allowed in.[
