I cannot access the related records for editing in the experience builder app using the edit widget. I can edit the parent layer's (Entity) attributes but I cannot even view/edit the related records in the experience builder edit widget. I want to give users the ability to add related records to the parent feature layer and also update/edit them as needed. Am I missing a step? See in the attached screenshot. I have the contacts for related records, entity as the parent layer.
In map viewer, here is what it looks like in the smart forms:
This does work—I have it set up in multiple Experience Builder apps. You just need to bring the related records over using Smart Forms. Then in Experience Builder, click on the layer and select "Use web map settings" so it knows to apply your Smart Form configurations.
Also what version are you using?
