My intention is to georeference an image so as to create a Swipe Map in AGOL. First, I add my control points, rectify, then analyze before attempting to share and finally publish in AGOL. The other day I ran through these steps and it worked fine. I was able to then create the app for a simple Swipe Map. Using the same steps while adding another image to the same map back in Desktop I now continually get the spatial reference undefined error when analyzing. Or the newly created projection through rectifying just disappears and I have to add the control points all over again.
I've added some screenshots.
Thanks for any help.
