I am using ArcGIS Pro 2.6.
I have a layer (A) with a label class with a 50 point offset, a simple black box outline with a 2 point gap and a simple black leader line. I have another layer (B) in my map that I don't want the labels or their bounding boxes to overlap. I have set the feature weight and boundary weight of layer B to 1000.
However the bounding box of the labels overlaps the features. Is this not taken into account when preventing overlaps? The text does not overlap the features, so I am assuming that only the text is prevented from overlapping. Is this correct?
Are you still having issues with this? From what you're describing it sounds like you've set up the properties correctly. Does the label class on layer A have the never remove checkbox checked on? If not, would it be possible for you send a screenshot of the placement and placement properties?
