We are trying to get Excel For GIS up and running for our employees and all the references mention a "Add Attribute Table" toggle is present and active for Add From GIS when you add feature classes to the map pane. We are not seeing the toggle for our feature classes and have even played around with editing and sync settings to try to get the toggle to appear. Below is a screenshot of our Add From ArcGIS window and we are using the AGOL login credentials to access our information. I am having a hard time finding information on trouble shooting this problem, so any help is appreciated.
