relationship class fails to publish to arcgis online

[DaveCrooks]

Hi,

I'm trying to create relationship classes between a polygon feature layer and two survey tables (Before and After). However, when I attempt to publish the data to ArcGIS Online, the "Copy all data" option is not available.

Additionally, when I try to use an Arcade expression for symbology (to show field values from the "After" table), the expression does not recognize the relationship class name.
That said, I can still see the related tables listed under the layer in the ArcGIS Online content.

Could you please advise on how to resolve this?

Thank you!

Are you creating the relationship classes in fgdb and publishing via ArcGIS Pro?

Arcade in AGOL does not directly support accessing related records across a relationship class in symbology expressions. This is a known limitation.
The FeatureSetByRelationshipName function isn't available in the symbology profile.
