I have also had the ‘nothing happened’ panorama issue.
I also have experienced an issue where Affinity can’t make up its mind on how to create a panorama. I took 13 photos of a large storm building up over the mountains. When I attempted to create a panorama from the photo set, Affinity created two panoramas: one of the lower two-thirds of the scene and one of the upper third of the scene. However, when I created a panorama using only the _upper_ two-thirds of the scene, that panorama stitched correctly. So, I can get either the upper two-thirds or the lower two-thirds of the scene, but not the entire scene. Am I doing something wrong?
