Awesome. It's always bugged me adblock/ublock required a root. Adguard seems to work pretty well, at least for blocking ads on youtube.https://adguard.com/en/welcome.html
AdGaurd if you use Chrome on Android.
Mobile Chrome doesn't support extensions, and the built in adblocking sucks. Google removed the AdGaurd app from the Play store because it was decimating their ad revenue, but you can still download it from their site. Works like a charm.
