I added a WMS on ArcGIS Online in the webmap I am using for a WebApp.
The WMS is the following : http://wms.vd.ch/public/services/wmsVD/Mapserver/Wmsserver
When I try to use the web map in the WebApp via WebApp builder, it returns an error saying that it couldn't upload the wms.
Do you have any idea from where this error comes from ?
Thanks a lot
