We just started using Adobe Edge Animate to do our HTML 5 banner ads. So far it's been pretty good but once client has feedback and changes are needed we run into a lot of issues with updating the files. It either skews the images weird or it holds onto the old images in the library and uses that additional file size in its output. Is there a good way to update a PNG or SVG file without having to delete the whole thing? Flash did it fine so i would think Edge would be easy but we haven't had much luck.
