When you sign-in to adobe.com via Adobe: Creative, marketing, and document management solutions...Does your adobe-id work here?
Have you tried to use your e-mail as the user-name? If not please give it a try.
I can succesfully logon to the website, and can logon with my new password on my iPad.
If I use my email address in LIghtroom Desktop, it says my credentials are wrong.
sigh. of course, I try it this morning and it works. so i guess I really just needed to wait a day...
