I also have found recently it’s buggy in that when I enter the ID’s of the pages/posts to be excluded, it’s no longer storing them in the list. Upon refresh they are gone. In addition, the excluded pages/posts are still showing in the sitemap. With having a protected membership site, this is a problem.
I have cleared the cache on the site and re-entered the ID list, but there is no change. I toggled include categories to see if that made a change and it took it fine. So it’s updating, but just not correctly.
Last thing I noticed is new categories to exclude always show up at the bottom of the list, making it not user-friendly to have to scroll down and find it (if you remember to do that). I would suggest making an option of exclude all categories except these ones (in my case, it would be exclude all but General, since it is a members site).
