I have an Experience for editing a point layer with a related inspection table. Structure is below:
The issue is I can view and add attachments in the Point layer editing window but I cannot do either in the Inspection table editing window. I've tried a workaround where I added a Feature Info element under the Inspection table editing window to display the attachment, but I'd prefer to just have 2 Editing elements side by side to view and edit attachments for both the feature and the inspection.
I have had the same issue and apparently this is either a bug or a feature that was never added according to ESRI. I am hoping that they are able to add this functionality soon as we have several workflows that would be greatly improved by being able to add attachments through ExB.
