I added several hosted layers using their URL from our organisation's Portal to ArcGIS online. I created a web map and used them to add tables to an Experience Builder app (blank template). However, the data does not show in the table while creating the app, when looking at a preview, or after publishing. When I add the data as an item directly to ArcGIS online, the values of the table do show up. All other widgets work perfectly when adding items with the portal URL. I can even export the table and filter results, but it just doesn't show the values. Due to limitations of our ArcGIS Enterprise license and confidentiality of the data, I cannot upload directly the layers to ArcGIS online.
Could this be a bug of the ArcGIS online table widget?
