I've enabled the Skitch extension, but it doesn't appear to be working. I find an image I want to mark up in my camera roll in the photos app, tap the share icon, and tap on the Skitch extension icon (in grey). The image opens up in a skitch window, and I proceed to mark it up. I then tap "done", but am returned to my original image with no markups. There is no second marked up copy to be found anywhere. So instead of "done" I tried "export" from the menu. It opens up the export screen with the original image selected, minus markups, and no matter what I tap on from there, I'm working with the original; still no markups. What on earth is going on? Works fine if I open the image from inside Skitch instead BTW, it's just the otentially very handy extension that's pants.
