Thanks for the quick response Owen!
The reason I am not a fan of "click anywhere to interact" is the maps I have published, the only function is to zoom in/out, not to interact with the data. I have uploaded these maps as a visualization and not exploratory, so saying "interact" could be confusing to some individuals, since the only option of the map is to zoom and change the extent. Having a customizable message or just a few choices for a message is all I am looking for.
I have received this feedback from my team along with just the map interaction in general. It can be slightly confusing to start interacting with applications and then figuring out how to stop interacting. I constantly overlook individuals who are less experienced with interactive application on AGOL, so it is hard for me to relate to this issue.
Possibly drawing more attention to the stop interaction button might also be something ESRI wants to look at.
Hope this helps, Joe
