Norton Safe Search question

Why doesn't  my Norton Safe Search work with the Bing search engine anymore?

 

It worked just fine for many, many months.  I had always looked at the Norton check marks assigned to each of the items in my search results.

 

Now I do not see the Norton check marks when I use Bing. 

 

Bing has changed something...  I'd really like Norton Safe Search to work again with Bing.
