Resampling option in WMTS Layer

[PauPérez_Puigcerver]

I'm using API version 3.22, and I have LODs defined up to level 20 on the map:

var lods = [{"level":"4","resolution":9783.93962050256,"scale":3.6978669431820706E7},

                            {"level":"5","resolution":4891.96981025128,"scale":1.8489334715910353E7},

                            {"level":"6","resolution":2445.98490512564,"scale":9244667.357955176},

                            {"level":"7","resolution":1222.99245256282,"scale":4622333.678977588},

                            {"level":"8","resolution":611.49622628141,"scale":2311166.839488794},

                            {"level":"9","resolution":305.74811314070485,"scale":1155583.4197443961},

                            {"level":"10","resolution":152.8740565703525,"scale":577791.7098721985},

                            {"level":"11","resolution":76.43702828517624,"scale":288895.8549360992},

                            {"level":"12","resolution":38.21851414258813,"scale":144447.92746804963},

                            {"level":"13","resolution":19.10925707129406,"scale":72223.9637340248},

                            {"level":"14","resolution":9.554628535647032,"scale":36111.98186701241},

                            {"level":"15","resolution":4.777314267823516,"scale":18055.990933506204},

                            {"level":"16","resolution":2.388657133911758,"scale":9027.995466753102},

                            {"level":"17","resolution":1.194328566955879,"scale":4513.997733376551},

                            {"level":"18","resolution":0.5971642834779395,"scale":2256.9988666882755},

                            {"level":"19","resolution":0.2985821417,"scale":1128.4994331969},

                            {"level":"20","resolution":0.14929107085,"scale":564.24971659845}];

I have layers in the HTML viewer that reach level 20, but there are others that go up to 19, and I would like to avoid caching these layers to this last level. I have tried adding the resampling = true option when I add the layer, but nothing is displayed at level 20:

var options = {

            id: servicioId + ";",

            serviceMode: "KVP",

            resampling: true,

            //maxScale: 400,

            /*resourceInfo: resourceInfo,

            layerInfo: layerInfo,*/

            visible: true

};

        var capaAnadida = new WMTSLayer(urlWMTS, options);

I am doing something wrong? Is there any other option?

Thanks!!
