I have already seen identical questions - here and here.
I've tried all the solutions posted, checking the redirect URL in the Admin console, and deleting all cookies. However, I keep getting redirected to the Gmail login page.
I've even tried the long form of the URL (https://www.google.com/a/example.com) but that also doesn't seem to work.
Could this be because we have the FREE version? It used to work earlier though.
Any help would be greatly appreciated.
