Remove ad button doesnt work

Good app with lots of recipes that sound delicious, but Ive clicked on the remove ads button and it doesnt work. It would be nice to read a recipe without ads popping up every time. The ad that never disappears at the bottom is annoying too because it blocks the last recipe in the list.
