Would you please try the below code snippet with 21.11 version of the API and let us know in case you still notice any issues:

Document doc = new Document(dataDir + "rule_builder_N_All_Security.pdf");
double zoom;
GoToAction action;
if (doc.OpenAction == null)
{
     //Document has no action, magnification is null

     //Create new GoToAction
     action = new GoToAction(new XYZExplicitDestination(1, 0, doc.Pages[1].PageInfo.Height, 2));
     doc.OpenAction = action;
     zoom = (action.Destination as XYZExplicitDestination).Zoom;
}
else
{
     action = doc.OpenAction as GoToAction;
     if (action.Destination is XYZExplicitDestination)
     {
         zoom = ((XYZExplicitDestination) action.Destination).Zoom;
     }
}
