Hi @BethRomero,
This app was created in instant apps and is now not showing the introduction panel on open as well. The Interactive Legend template was not what I originally built this app from, so I'm not sure what piece is not being updated to the new functionalities when I republish.

In fact, the introduction panel widget button isn't working at all despite being configured properly in the instant app builder. The introduction panel does not work in incognito mode either. I built out the intro panel information into the custom header, but unfortunately that isn't mobile responsive without significant time spent on custom css and html.
Any ideas of what to try next?
