I had raw images that I added to the Lightroom app to create presets. I've added all the presets in my Lightroom mobile app. But while editing an image when I select any of the added preset, there's no change in my pic. They are not being applied on my pic I don't know why.
Looks like something went wrong with the creation of the presets. All the previews show the same image as the original, meaning that the presets don't do anything. Maybe you didn't check any options when you created the preset? Maybe you created them from an image that was not edited? How did you create them?
