Problems with Email on Yahoo

On day 2 of the transition, I decided NO MORE ADS, so I do have Yahoo Plus for $5 month. However, I have ta similar problem to yours today with a verification code email from a US govt site. Logging into your Social Security Admin. account requires 2-step verification, and before the Cox-Yahoo transition I chose to receive the verification code at my cox.net email address. Today I tried multiple times to receive the SSA verification code to log in to my SSA account. But no luck -- no email came through on Yahoo Plus. I believe that for security reasons, certain personal emails from US govt sites will require you to set up a new way to receive the verification code. With the SSA, the only way you can make a change is by SNAIL MAIL! I just requested to received a one-time verification code by snail mail. It will take 5-10 business days, the SSA said. Then I can log in and change receipt of the code to my cell phone. This is a pain, and will be even more painful if I DON'T receive the snail mail code.
