I am having the same problem. I have Iphone 6s, and have successfully scanned 3 pages which could be saved to the photo roll. I signed into evernote through scannable but it will not save the scans to evernote and never created a "Scannable" notebook. I have closed, opened and re-synched evernote on evernote.com, mac and iphone still no scannable folder. Any other suggestions?
