urrgh. i use pi hole, ublock on firefox on desktops and android and i still find that sneaky ad creep in sometimes. makes me sick. newpipe helps a lot actually
This let's you block ads on a system level or as I do on my p30 Pro not let any of the system apps connect to the Internet.
seeing as I have no way to disable system apps as I'm not rooted.
