The tool shows up and is usable but I can’t get it to select the whole image. I haven’t noticed a difference between the file size or file type when trying to do this. I’ve actually tried to save the file between two different types and still get the same result. I can upload two images to my site, one that will show the whole image when trying to crop and another that won’t if that would be helpful. I can also give you the website for you to create an account on to see if you can get it to work.
