My symbols have text which is bleeding through overlaying points.
The process I used to get here:
I created the symbols in arcGIS Pro using two shape marker layers. (in this case, a circle and text) No bleeding in Pro
I added them to a custom style and exported the style to arcGIS Online.
Can you share the style or the layer & map with the style applied?
here is the style:
I can't share the layer or map as they contain client names and account numbers.
