In addition to our normal Knowledge Base that is found in the APAN Support area, I have added an additional area for assistance in getting started with the New Community Maps app. You can find it in the banner above under Need Help?
Did you know that this is built on the same software (ArcGIS API for JavaScript) as our Portal? The reason for replacing the Google Maps API was to build familiarity with the interactions of the new Community Maps and having a working knowledge of how to interact with the products of our Portal for ArcGIS on APAN.
Is there is a feature you would like to see incorporated with the new API, start a conversation or respond to this post and we as a team can discuss.
Happy Mapping!!
