ArcGIS Online not displaying curves correctly

Question

In our water network data we use "loops" in lines to display areas where pipes overlap but do not intersect.  We noticed yesterday that in ArcGIS Online (Experience Builder and Field Maps) that the curves are drawing with much less detail.

This is what they look like in ArcGIS Pro:

And this is what they look like in ArcGIS Online:

I checked the settings of the layer and confirmed that we are not using the "Optimize layers" setting to increase drawing speed.  For reference, the layers in ArcGIS Pro are coming from our enterprise geodatabase via services from ArcGIS Enterprise, and the data is published to a hosted feature layer in ArcGIS Online.

Yes - I have the same issue. Curves should be displayed as curves OR at best not simplified so much. Many of our drawings and map require a higher level of detail than the map viewer is allowing.

Is there a fix coming for this?

Hi Kennedy - Do you mean that curves for road and bridge are the same but displayed differently on Map Viewer (the green/gray overlap in the image)? If so, please attach the data here so we can take a look. Thanks!

Hi,

I'm seeing posts from 2023 saying AGOL should approximate the curves. It wasn't working for some and it was a bug back in 2023. I have been painstakingly drawing parking lots, sidewalks and roads with many curves and now when published to AGOL, the roads/sidewalks overlap in places because of the straight segments. See the green/gray overlap in image. What's worse is the light brown pedestrian bridge that goes over a road shows completely disjointed and messed up.
