Luescher review: Technical

Hi,
I did install DDG on my desktop as well as on my iPhone and iPad.

Question: on my iPhone and iPad I do see the A-F protection categorie of each website I visit. However, after having installed the DDG extensions (privacy protection and privacy dashboard) on my Mac, I always see the D category on top, while visiting a webpage. Why does this not change from one to the other website and always shows „D" protection category?

Pls revert and thanks for your help/information.
