@Seb Z , From your description, it seems you are enrolling device into Intune. But it seems the device is only Azure AD joined. Not enroll into Intune. If there's any misunderstanding, please let us know.
To troubleshoot our issue, please check the following information:
- Please check if the user we used to enroll the device has Microsoft Intune license and Azure AD Premium license assigned.
- Please check the automatic enrollment configuration to see if the "MDM user scope" is set as ALL and if the "MAM user scope is set none".
- Did we get any error when we enroll the device?
- How many devices are affected? What are the platform of them? What enrollment method we used?
