I have a series of layers I've published to vector layers in order to create a custom basemap I had intended to use on a series of WebApps I will be producing. The issue arises when I go to add the (vector tile, hosted) layer(s) to the WebMap; ArcOnline complains of coordinate system or tiling scheme conflicts (see the shared image). Some of the layers I've hosted will add to the WebMap, others refuse, and it doesn't seem to be a coordinate system issue. Has anyone else run into this? Fairly new to vector tiles.
