Acrobat Sign Developer Edition Account — Registration Email Not Received After Multiple Submissions

I have submitted the official form for a free Adobe Acrobat Sign Developer Edition account multiple times, but I still haven't received the account activation or access email.

I need this account urgently for API integration development and testing. I have checked my inbox and spam folders, but there is no email from Adobe regarding my registration.

I already have access to Adobe Developer Console, but when I try to access the Adobe Acrobat Sign API, I receive the following message:

"License required. Your organization does not have a license to access this API. Please contact your admin. If you think this is an error, please contact customer support."

I understand that Developer Console access and an Acrobat Sign Developer Edition account may be separate. I am specifically trying to obtain the free Developer Edition account for API testing.

Could an Adobe representative please check whether my registration request is pending, whether my email address is already associated with an Acrobat Sign account, or whether any other issue is preventing the account email from being sent?

I have resubmitted the registration form, but I still haven't received anything. Any guidance from someone who has successfully obtained access or from an Adobe representative would be greatly appreciated.

Thank you.
