Ismael was very helpful with my 1st question. I do have another. But first some background. My grandfather served with the American Expeditionary Force in France during WW1 or "la Grand Guerre". Over the past 2 years I have built a story map describing this.

I will travel to France next month to retrace part of this route. This QuickCapture tool has allowed me to rapidly develop a way to gather data in the field, and post it to my story map as I go. I will travel in parts of France where there may be no cell phone service. I've read the QuickCapture can gather data off-line, and then sync with AGOL later. How does this work? What do I need to do to enable this?
