I want to use AG Earth (version 1.8) so I can provide a KMZ with a different basemap. Unfortunately, the basemap will not resolve when zooming in closer than the whole earth. When I open up the basemap icon, all of the basemap thumbnails are imbedded with an orange triangle containing an exclamation mark and I can't change the basemap. I signed into both my portal and AGOL accounts with the same result, and the basemaps function normally in AGOL and ArcGIS Pro. Has any one run across this problem? Thank you...
