I have an iPad Pro and the app Graphic by Autodesk. Graphic can export SVG files but as of right now there is no way to get that SVG to VIdeoscribe without going to my computer and importing it there. Graphic supports saving to Dropbox and iClound and it would be great if that functionality was added to VideoScribe. It would give it the same functionality as the desktop version!
Interesting suggestion I have found on another forum which is making the folder in DropBox public and then you can use the web-link functionality to pull that image in. Just tested this on the iPad and works fine.
