Platform Single Sign-On for macOS device registration fails consistently
in Preview Sandbox org, even with Device Access (Dynamic SCEP, Okta CA)
configured.
Please confirm whether macOS Platform SSO device enrollment is supported
in Preview Sandbox (oktapreview.com) tenants.

Hello @0.59475 (Customer) If the Preview environment is linked with a Paid Okta Service then you should be able to follow the instructions below to open a case:
