The June 2019 update of ArcGIS Online has a great new configurable webapp that highlights and makes easy to view attachments. The app is slick and runs well, but the problem is that you can only view the attachments for one selected feature layer. We have have a workflow that requires the collection of multiple different types or classes of features that are represented by points, lines, and polygons. Letting the app user select the multiple feature layers with attachments to explore would be ideal. Is there a work around that allows me to configure the app so that the viewer can switch between layers?
This idea was implemented in the October 2019 release of ArcGIS Online. For some more information about this, and other improvements made to the Attachment Viewer App at this release, check out the following blog: What’s New with Attachment Viewer
