Why is eBiller such a pain? not giving the option to enter the 2FA code

in2ndo

I don't have many bills linked to eBiller and every time I try to add a new one, I have to try multiple times to finally get a response. and if they have 2FA enabled, some times it gives the option to add the 2FA code and some times it doesn't.

Yesterday I added AT&T after trying a few times and finally getting a response. it completed with the ability to enter the 2FA code.

Today I'm trying to add T-Mobile and most of the time it doesn't give me the option to request the 2FA code and when it does, it just gives me this screen and not the option to enter the 2FA code that I received on the cellphone.
