"Your organization does not allow access to third party applications" when connecting Claude — on an individual account

Hi all,

When I try to connect the Adobe connector (Adobe for creativity) from Claude, the Adobe sign-in window shows: "Your organization does not allow access to third party applications." and the connection never completes.

What I've already checked:
- My account is an individual Creative Cloud Standard plan (confirmed by Adobe support over the phone).
- account.adobe.com shows only my personal profile. No profile selection screen appears at sign-in, and there is no "switch profile" option.
- I signed out of all devices and signed back in.
- Tried multiple browsers, with the same result.
- I am not a member of any Adobe organization as far as I know.

Adobe support told me to post here. Has anyone with an individual account solved this? Is there a hidden organization/business profile linked to an email that only Adobe can see or remove?

Thanks in advance.
