Thanks for reaching out to us!
I believe that you’re using our program version. Nothing has changed here with our Black & White effect painting – it should work as it always has.
What’s the exact issue you’re experiencing? Is it to do with being close to the edge of the image or something else? If you aren’t even seeing the option, try click the “Effect Painting” button within the Black & White effect options on the left bar.
