An APNS certificate is in place. It was observed that when creating an enrollment policy—specifically by setting it as the default policy for an ABM account and selecting an Apple Business Manager account—the downloaded enrollment JSON file includes an encoded suffix in the BaseURL (e.g., https://domain/enrollment/apple/accountDriven/userEnroll/95444d5f-e7ae-4f23-9095-0ce7eb242e9b). Placing this specific JSON file at the discovery endpoint successfully initiates enrollment. However, if the JSON is downloaded via the action menu in the enrollment policy list, or by clicking "Download JSON" on the final page while editing the policy, the resulting file lacks that suffix (e.g., 95444d5f-e7ae-4f23-9095-0ce7eb242e9b). Placing this suffix-less JSON at the discovery endpoint fails to trigger enrollment and results in an error.
