Ever since I downloaded the most recent update, the “denoise” feature no longer works. I have tried all of the ways to strengthen the denoise and nothing happens, the picture remains the same. I have to revert to Photoshop to denoise a picture and I paid Topaz specifically to repair noisy images.

You may need to adjust the Selection option while using the Denoise feature to ensure the proper Subject or All of the image receive this edit.
