Previously working map with several layers doesn't display when workbook reopened. Just see the ArcGIS for Excel icons and white space where the map should display. See attached screenshot.
I can see the list of layers if I click on the layers icon, but clicking the carat icon for each just shows "No legend". Signing in again doesn't help.
Using ArcGIS Enterprise 10.9.1.
Any ideas what might cause this? Thanks!
