I have the same problem. I am using Chrome. I cannot access the portfolio. Started Saturday morning! After I added a new portfolio! Not sure what is going on!
This must be something gto do with the browsers. I only use Chrome and I cannot sign in "My Portfolio". Just tired Firefox, it works! Very strange! What are we supposed to do?
