Policy CSP - ADMX_Thumbnails
Tip
This CSP contains ADMX-backed policies which require a special SyncML format to enable or disable. You must specify the data type in the SyncML as <Format>chr</Format>. For details, see Understanding ADMX-backed policies.
The payload of the SyncML must be XML-encoded; for this XML encoding, there are a variety of online encoders that you can use. To avoid encoding the payload, you can use CDATA if your MDM supports it. For more information, see CDATA Sections.
