I am providing access to some WMTS through our Enterprise Portal, and I am struggling getting my name of the credits when showing the service in a layout in ArcGIS Pro.
I went through all metadata, general information and settings of the WMTS and the only place where these information are referenced is the owner. In the 'Credits (Attribution)' section I tried to simply place an empty space in, but it does not alter the behaviour of the layer in the layout.
Since the information shown in the credits area can only come from the portal I was wondering on how I can adjust it.
