When cropping, I switch from Original aspect ration to Custom, then I drag crop area on the image but it still behave like Original. When I hover my cursor over crop settings, it switches to Original aspect ratio itself. I found no way how to perform free cropping.
This thread aligns with what I'm trying to do. I can unlock the constraint on aspect ratio and arrange the crop as desired, but I don't see a way to enter a custom ratio numerically, e.g. for a social media page image.
