in addition to what costurbousr first stated above
I am on a MAC
I also ensured Safari was NOT my default browser (set Chrome as my default)
I purged cache and cookies for Safari and Chrome
I reset my Intuit password (I think this may have finally did it but still uncertain)
stoped my browser running in the background
Eventually it started to work - did the above help ? Maybe. was one of the above the key to resolving the issue or did the gods finally said OK we will let it work for you. I think it was the later.
