See attached screenshots, rotated symbology doesn't seem to be honoured in AGOL.
I submitted same re: Antarctic project under WebScene. Then I thought this was because I re-projected WGS84 into Polar Azimuthal on-the-fly. So for its Arctic mirror, I re-projected everything to Alaska Polar, to match the Arctic Ocean base-map. But I still get all arrows pointing N in AGOL, posted, whereas they point in wind direction in ArcGIS Pro, package also posted. Anyone have this problem, &/or a solution? I tooled around and haven't found one yet...
