Apple TVs authorization is required not working to play purchased library

Apple TV is now refusing to authorize purchased movies from a desktop Library thru the Computer app. Gives an AUTHORIZATION IS REQUIRED message repeatedly. Other content plays fine. This error occurs on both a 2nd & 3rd gen ATVs. In past would have to re-authorize computer occasionally or sometimes have to cycle the Home Sharing for ATV to find computer. Other devices iPhone iPad do not have this problem. Found same issue in a post dated May 30, 2022, but no fix given.
