Application Guard Favorites Sync Enabled

This policy allows Microsoft Edge computers/devices that have application guard enabled to sync favorites from the host to the container so the favorites match. If 'ManagedFavorites' (Configure favorites) are configured, those favorites are also synced to the container. If you enable this policy, editing favorites in the container is disabled. So, the add favorites and add favorites folder buttons are blurred out in the UI of the container browser. If you disable or don't configure this policy, favorites on the host won't be shared to the container.
