Login takes you to "Start Free Account" page?
Has anyone else seen this (Firefox)?
When you are signed in with your Adobe CC account, open a new page for CCExpress. The landing page doesn't recognize that you already have an account - despite showing that you are signed in (upper right corner).
Is this something unique to Firefox?
or Is this the landing page for everyone?
I know that Firefox browser has had other troubles with ACS.
It should take you immediately to your Home or (better) Projects page.
