Why is my device not compliant when I've done everything I'm supposed to do?

The compliance status in MyDevices is not updated instantaneously. Changes that you make to your device can take up to one day to be reflected in MyDevices. For this reason you should not wait until the last minute if you are notified that your device is not compliant.
Make sure your device has connected to the Internet in the last 90 days. Go to mydevices.stanford.edu and then click the link in the Model column to display the Device Details page of the non-compliant device. Check the "Last Check in Time" entry to verify your device is checking in.
If the device has access to High Risk Data, be sure BigFix (for Windows) or Jamf (for macOS) is installed and configured with Stanford Device Registration.
If BigFix is installed but in MyDevices, the Management System Information section is missing, incorrect, or out-of-date (see the "Last Check-in Time"), there might be a problem with BigFix. Please submit a Help ticket.
If the Mobile Device Management (MDM) service is required for your iOS or Android mobile device, go to the Device Details page in MyDevices. In the Management System Information section, confirm that MDM is indicated as the management system.
