The Slider Instant App is a great add-on to ArcGIS Online. Slider is used over here in an application that has compiled information about the grid connection possibilities in different time periods as well as production projects that are already being planned or implemented.
Do you know when multi-layer support will be released in the Slider Instant App? If multi-layer support is being worked on by the development team, is there any information on the timing of this release? It is mentioned here that the release would be coming “sometime in early 2022”.
