Please include a scroll bar in the Introduction panel in Nearby Instant App.
If the Introduction panel is included in the App (not as a splash screen) it is impossible to scroll. Any information not displayed is lost.
A coworker found a work around to if the Introduction panel is Opened as a splash screen, you can scroll.
In the intro panel is where we include important information and need to be readable on all screen sizes.
@RyanBohan thank you for reporting this, it will be resolved in the next update of ArcGIS Online.
