Hi,
I used the new ArcGIS Assistant to copy an Experience Builder app from my ArcGIS Online account to my Portal 10.9.1. When I try to open the experience on Portal I get "Oops.. It seems this experience is built with a higher version of ArcGIS Experience Builder. Please upgrade to the latest version to view."
I purposely did not use any widgets that are not available in Portal yet so I assumed I'd still be able to open it.
Is there any way to view and open my ExB app in Portal? How do I upgrade? Can I do it if I install the developer edition? Recreating the whole Experience from scratch would be a massive undertaking.
Thanks!
