Trying to change our email address and keep getting the message "There were some errors with your submission. Please double check and re-enter or try a different email". The email we're trying to change it has never been used before (in fact we've now tried a few and had the same message just to be sure). Also the password is correct that we're entering and confirming with.
I think you have to confirm the current email before entering the new one.
There's 3 boxes, which are to confirm your new email (twice) then the password.
