I've added the Basemap Gallery tool to my webmap and when you open the tool all the thumbnails show up, but when you click on one to change the basemap, nothing happens. Do I need to enable the basemaps somehow in the ArcOnline step or is this something that needs fixed in the WAB? I can't find any steps that I missed in the setup, does anyone have any ideas?
Note: I am not a programmer, so please be very basic with your answers. Thank you!!!
