From the DVC site:

"Update to Disney Vacation Club Resort Access for Contracts Not Purchased Directly from Disney

Effective January 19, 2019, only Members who purchase directly from Disney will be able to use their Vacation Points at the 14 existing Disney Vacation Club Resorts or future Resorts—such as Disney’s Riviera Resort or Reflections – A Disney Lakeside Lodge. Resale contracts purchased for the existing 14 Disney Vacation Club Resorts will only be able to exchange Points into those 14 Resorts.
This change does not apply to contracts purchased prior to January 19, 2019. Contracts gifted to family members will continue to have the same Resort access as before the ownership transfer.
The eligibility rules for Membership Extras and RCI access remain unchanged.
The Buena Vista Trading Company Disclosure Guide has been amended accordingly."
