Will Error 400 ever get fixed?

I check the Team Builder website every day (I probably shouldn't at this point) hoping that this issue is fixed and I can do what I love and that is create my Team Builder teams and play them on the consoles. I have 14 created and I want my other 18 which will give me 32 total as promised. I have researched youtube on how to fix this and nothing that was suggested has work. I tried new browsers and still nothing works. Can anyone please tell me how to get around this or do I have to wait until CFB 26 come out? Why is it still in beta mode? It will be a year this July and still showing beta. Can this be patched or something? Team Builder is my thing and that is what I love the most about CFB 25. If somone can help me understand this please help me.
