Collector for ArcGIS is the great application for surveying indeed. Unfortunately, after the process of collecting data using Collector for ArcGIS, donwloading the attachments from ArcGIS Online takes a long time to finish.
It would be great if we can download all of the attachments to our local storage at once! As one ZIP file or a folder, whatever. We can save time a lot!
I hope this would be helpful for us and our customers if it's implemented somehow.
