OAuth Token Issue Affecting E-Prescriptions and HIN Sign

We are currently experiencing an issue affecting the use of OAuth tokens for the following services: - Creation of e-prescriptions (E-Rezept) - Use of HIN Sign It is currently not possible to issue e-prescriptions via OAuth token, and HIN Sign is also not functioning when using OAuth authentication. This issue also affects the generation of tokens through practice software integrations. Important: Already active OAuth tokens remain valid and continue to function as expected. We are actively investigating the root cause and will provide updates as soon as more information becomes available. We apologize for the inconvenience and appreciate your understanding.
