Web App users are able to query data of relating tables (via relationship classes) in the popup window of the corresponding web app (see https://support.esri.com/en/technical-article/000012168).
Our problem is:
We can't get related data to be shown up in the corresponding attribute table widget in the web app, nor are we able to use related data for labeling point features. Using the web app popup window related data is not shown directly, but over several clicks in the related table section. Not very handy...
Is there no support for related tables in the attribute table widget and as text label information, or did we make some mistake when publishing our relationship classes / feature classes?
Or do we have to customize the attribute table widget?
