So, I'm aware that ArcGIS Pro arrow symbols for line features are not compatible with ArcGIS Online web maps (especially the new Map Viewer). I also know that ArcGIS Online has its own arrow styles, which do not separate the shape marker from the stroke. Is it possible to bring ArcGIS Online's arrow styles into ArcGIS Pro?
I ask because I have a map service (published from ArcGIS Pro) that I use for an ArcGIS Online web map, and one of the layers in that map service uses an arrow symbol to represent its line features. Presently, if I were save that web map in the new Map Viewer, that layer would immediately be converted into thick black lines. I know I could manually change the symbology in ArcGIS Online after republishing the map service, but cutting out that step would be more ideal.
Update: I may have been mistaken about the compatibility issue, it looks like it's only occurring with that specific map service for some reason; I'm unable to replicate it with a new map service and web map.
