I just went through a lot of work to configure an Instant App using the "Web Editor" template, but I discovered that pop-ups are not working in the app. I enabled and configured pop-ups in the Map Viewer, and they work there. I re-saved the map and re-published and re-launched my app. But still no pop-ups - I click on a point and nothing happens. Does anyone know what is going on with this? Are pop-ups somehow not allowed in this template?!
