v3 API not allowing me to add contacts.

[JenniferS1215]

Hello. I seem to be having some issues with your v3 API.

I am able to authenticate with the contact_data and offline_access scopes. I store the access token on our database and it is pulled and refreshed.

However, when I try to add a contact with the sign_up_form endpoint it returns this:

{"error_key":"access_denied","error_message":" Request forbidden due to insufficient authorization scopes. Request forbidden due to insufficient user privileges."}

I don't understand why I am getting this error, as I authorized the application with the contact_data scope and the only user on our account is the account owner. Also, why is there no place on your account portal to deauthorize applications from accessing our user data?
