Is there a live page similar to the tale of two MapViewers that shows the functionality in each MapViewer for each platform?
We used the Premium Feature data store and I think the timeline for that is different from AGOL.
We need to use analysis tools in AGOL.
We also use ArcGIS Enterprise 10.9 in Azure and need to use FieldMaps. I think we need to keep using MapViewer Classic for that project for a while.
