I just saw a message saying about category filtering at my adsense acount. I follow the links etc then I saw "category filtering" settings available at my account.
I just blocked 2-3 categories and then I saved it.
Then I came back to the same section again, but there is no " category filtering settings" available at that time.
1- Is this normal?
2- What happened to categories that I just blocked 10 minues ago?
