We are being asked to replace all of our basemaps with US Edition (Gulf of America) and I am having trouble doing this with my older WAB Developer applications. Esri docs say that the 3x api considers basemaps to be operational layers and this is not the case with the 4x api. I tried replacing the basemap id in the main config file with an id from a US Edition basemap, but the app fails to load. Probably just missing something, but I have been working with EB for the last year and a half and forgotten a lot when it comes to WAB.
