Hello all. I am trying to add an extent indicator map to a map series project in Pro. My problem is I cannot get the indicator map to act independently of the main Map Frame. When I turn on/off a layer in the indicator map, the same layer is turned on/off in the main Map Frame. I do not want this. I want to be able to have control over the indicator map like I do in ArcMap, where, once "Activated", the inset map operates like a separate entity where layers can be added, labeled, symbology changed, etc., without affecting the main map. Any ideas on how to achieve this? I tried "locking the element", but that did not work. I tried R clicking on the Map Frame & choosing "Activate", and that did not work. I reviewed help documents & videos, & no one else seems to have that problem. Any help is appreciated, Thank you!
