So I decided to start a new account with a new Yahoo mail account. I was able to do the initial setup, then the system sent a confirming email to my yahoo account. That worked fine.
I quickly clicked on the confirming email message.
I got stuck on the Please wait message for at least 30 minutes. Then the following message occurred.
From this point on, despite several login attempts for off and on for the rest of the day, I never got past a white screen or the infamous 3 circles.
