I have gone through this project and assured all layers and features are marked share public, but the application is still requiring individuals to log in to see everything. This is a problem because it was created for individuals who are not ArcGIS account holders.
Here is the app link: https://experience.arcgis.com/experience/841ec133761b445a8e1e33ae9953b753
Please let me know if there is anything I can do to fix this. The map is public, but when in the application, it is not.
