I'm trying to move an application from ArcGIS Online to Portal for ArcGIS 10.6.1. I managed to move the app, but I'm getting strange behavior regarding the search widget. In AGOL, when I perform search using an attribute query, it displays the popup I configured for the layer along with other features at the same location. In Portal 10.6.1, it displays a default popup with unconfigured fields. It also displays an opaque graphic over the feature which obscures the symbology. I am okay with the blue outline, but I don't want another color patch on top. I noticed Portal 10.6.1 uses WAB 2.8 versus WAB 2.15. Is this the reason for the difference? I want the search to open a popup, but I want it to be the one I configured, not just all the attributes returned by the search.
