I recently configured a version of the Zone Lookup Instant App, showing results from a feature class with two related tables. The data from the feature class and tables is in an ArcGIS Online hosted feature layer, which supports related tables in popups. I've confirmed that the results show correctly in popups when using two related tables.
In the Zone Lookup app, however, I run into a strange issue when showing related tables. Only one of the related tables shows with all results, while the OBJECTIDs from the second related query are used to add more results to the first table, showing extra values in the first table that don't relate.
I've even tried removing one or both relationship displays in the popup, but the first related table appears with extra values that would have been used for the second related table.
I hope that all made sense...
