Now that ArcGIS Online allows true curves, we have published our parcel data to pull down into ArcGIS Pro. This allows multiple editors at the same time. The issue is that when ArcGIS Pro renders our parcel data and True Curves are enabled on the Hosted Feature Service, the way it renders shows large circles and arcs all over the map that don't actually exist in the data. If you view the images below, you will see the first one shows what the parcels look like when they are in a file geodatabase and the second screenshot shows how ArcGIS Pro is rendering them when they are published as a hosted feature service with true curves enabled.
@KaraUtter2 does Check Geometry on the original data return any errors?
