The Add Video to Map Viewer is a very nice feature. However, it can be further enhanced by having the ability to play videos attached to a Survey 123 form hosted point feature layer. So, let's say there are 5 form submissions, so 5 points in the feature layer, and each point has a video attached to it either recorded or uploaded from the mobile device. Then on Map Viewer, for example, when the user clicks on one the points, its video can then played.
