How does `CF_INSYNC_POLICY_NONE` differ from `CF_INSYNC_POLICY_PRESERVE_INSYNC_FOR_SYNC_ENGINE`? (cfapi)

For a CF_INSYNC_POLICY, the fields CF_INSYNC_POLICY_NONE and CF_INSYNC_POLICY_PRESERVE_INSYNC_FOR_SYNC_ENGINE are both two separate values. I know the latter prevents the platform from clearing the in sync state at all, but how does this differ from the former policy?

    Hello, @oknick

    CF_INSYNC_POLICY_NONE = 0, it means non in-sync policy is set. However, CF_INSYNC_POLICY_PRESERVE_INSYNC_FOR_SYNC_ENGINE is a flag used to exempt all of the other policies. It can be a kind of switch or flag to temporarily disable the existing policies without removing the policies. Just set/clear the flag can disable/enable the in-sync policies.
