We are trying to use a WMTS layer provided by the city of Kiel using ArcGIS Server. See this fiddle: https://jsfiddle.net/winnewoerp/p70mcn81/34/
See XML data here: https://ims.kiel.de/geodatenextern/rest/services/Basis_Internet/Internet_basis_grau/MapServer/WMTS?r...
As you can see, we're currently not using the correct CRS (EPSG:4647) to display these tiles within the above JS fiddle:
https://ims.kiel.de/geodatenextern/rest/services/Basis_Internet/Internet_basis/MapServer/WMTS/tile/1...
So no wonder things get messed up. But we didn't find a solution to display the tiles using EPSG:4647.
We're not sure if this is an ESRI issue or rather related to Leaflet (version conflict?) or Proj4/Proj4Leaflet. Any hints that point us to the right direction are welcome. Thank you!
