@JoshWhite I empathize. Herein lies the problem w/ Esri, in that they are pushing new platforms which are supposed to supersede existing platforms, which are NOT ready for primetime. In this case, Experience Builder w/r/t Web Appbuilder. Esri should never have pushed out EB until they made available at least what is available in WAB, and provided good, clear, thorough documentation for EB (having been an IT tech writer, the EB docs often leave me shaking my head). It is the same thing with the AGOL MapViewer, which is replacing MapViewer Classic.
I wish Esri would stop with the Force It Out Today, Fix Tomorrow (FIOTFIT) approach to their software. For a GIS developer like me, it is very, very frustrating. Sorry, but I had to vent!
