I'm designing an ArcGIS JS 4.x web application, internally hosted and internally viewed only (not publicly accessible). It'll include a basemap gallery with ESRI hosted basemaps. Upon previewing the application, our test users find "Sources: Esri, HERE, Garmin, USGS,...etc." to be annoying and distracting in the layout when using the print service to export to PDF. They'll have the option to choose a "map_only" or custom print template (portrait or layout).
With this being said, I need a little clarification regarding attribution requirements.
In the PrintTemplate API page, it says this for attributionVisible: "When false, the attribution is not displayed on the printout. This only applies when the layout value is map-only."
Are we allowed to hide attribution for "map_only" exports, or is the ESRI AGO basemap credit required for all print templates? I didn't see this explicitly stated. Is there any exception with live or printed maps that I may have overlooked? Just double-checking.
