We use Auth0 social authentication tools, including Google and Linkedin signups. Users received “The application is disabled” error when signing up with Linkedin.
Steps to reproduce
I saw this error after I deleted my application on LinkedIn (Developers | LinkedIn), so I understand someone deleted the app on the Linkedin side. I also tried using the wrong client ID and client secret for the connection, but the error was different for those scenarios.
Please open a ticket with Linkedin if you are the owner of the developer account for that application.
