Thank you for the reply @AlixVezina!
I reported a bug last week on the scroll but haven't heard a reply back yet.
For the related record Title and Sort. I am working with a REST Service and not a Hosted Feature Layer. It seems that the configurating of relationships in this way is only available for Hosted Features Layers. Using a Map Viewer and Field Maps you can add, update, delete related records from a REST Service, I was hoping to replicate this in the Experience Builder Editor Widget to provide our users a Desktop experience to edit data in addition to their current Mobile Field Maps. We used to use Web App Builder for the Desktop experience but are now using Forms with ARCADE calculations which is not available within Web App Builder, moving us to use Experience Builder.
The Feature to the 3 Tables have a relationship of GlobalID (Feature) to REL_GID (Table). Within Experience Builder Editor Widget, to get the related table records to select, I essentially recreated the relationship within the Map Widget > Action > Message action > Record selection change > Framework > Select Data Record > Feature (GlobalID) to Table (REL_GID). I created this action for all 3 tables. Therefore, when you select a Feature in the map, its related Table records are also selected which activates them in the Edit Widget, but the Title, Sort Order, and Scroll I have not been able to figure out how to customize.
