I just upgraded my portal from 11.0 to 11.2. Everything seems to be working for the most part but when I attempt to open an existing map in my portal's content, it will only open in the Map Viewer Classic and will not open in the "Map Viewer". I also noticed that I can no longer "Add New" in the portals content section, just a blank window opens. I'm wondering if these are related?
New item screen is blank
