Ask the MDM Administrator to display the package list in the "Certificate Revocation Check (CRL)" settings in the "Android Certificate" rule. 2. Verify the string is "*" (asterisk). 3. Ask the MDM Administrator to display the enable check box in the "Certificate Revocation Check (CRL)" settings in the "Android Certificate" rule. 4. Verify the check box is selected.
