I have installed AdGuard Pro and have installed all the filters.
Nearly every video I watch on Facebook (only when using my Android phone) becomes interrupted by a video ad.
In contrast, my partner also has AdGuard Pro on a Android and she experiences zero ads during facebook videos. It seems that we have the same setup, however I receive ads and she doesn't.
I have been trying to figure out how to block these ads for over 1 year.
