Could not get the latest orthophoto map for Poland

[anonymous]

What steps will reproduce the problem?

1. Try to add a new WMTS or WMS map like:

​https://mapy.geoportal.gov.pl/wss/service/PZGIK/ORTO/WMTS/HighResolution?SERVICE=WMTS&REQUEST=GetCapabilities

Or:

​https://mapy.geoportal.gov.pl/wss/service/PZGIK/ORTO/WMS/HighResolution?SERVICE=WMS&REQUEST=GetCapabilities

It works for the old map:

​https://mapy.geoportal.gov.pl/wss/service/WMTS/guest/wmts/ORTO?SERVICE=WMTS&REQUEST=GetCapabilities

What is the expected result?

A new layer added
