Hello
I'm running pi hole on my rasperry pi.
Since some weeks i'm facing the Problem, that my Mobile deviced aren't blocking all ads. (The most ads were Blocked for example on Chip.de)

How can this be?
Thanks in advance.

Thanks for the reply but i haven´t any other DNS.
Now i tried the privacy mode with the mobile and the ads are blocked.

Thanks in advance.
Edit: with the Chrome Beta the ads are blocked again
