I'm not sure if this is an option, and I just haven't been able to accomplish it yet. It seems like there should be a simple solution to making a collection on one device (Mac), and access the same collection (using loop) on another device (Iphone). I had made a collection on my mac device for the ease of navigation with the intent that I would later use it on my iphone app. It had not even occurred to me that it wouldn't be a possibility.
I love this program, and I really hope to see this function soon. If it's already possible, please let me know how.
