In my case, the patching work but installation failed. My solution is to save the generated apk and install it using a file manager instead of directly from revanced manager.
revanced is awesome. The patches are increasing in number. The one thing that confused me is what patches/options I can change later in the YouTube revanced settings.
So, maybe they could categorise the patches as:
Those that can be applied only while patching & cannot be changed in the settings.
Those that can be changed in the YouTube revanced settings.
I don't have a good ad blocker for you other than AdAway. It won't block YouTube ads on an unrooted phone, but it can on a rooted one. You can try in-browser mobile YouTube with Firefox + uBlock, but I would suggest switching away from the native YouTube app and getting NewPipe with SponsorBlock from F-Droid.
Highly recommended. You can even export your subscriptions from YouTube and import them into NewPipe. But that's for another thread. I use NewPipe almost exclusively now, having YouTube links pull up in NewPipe. No ads. And with SponsorBlock, you can skip the in-video ads (with community-driven data). Not to mention, you can also stream music from Bandcamp, and it supports PeerTube, etc, as well.
Alternatively, you can use the official YouTube site with Mull browser or Firefox with the ublock origin extension installed. But NewPipe offers a better experience since you can download videos etc.
I setup Firefox Nightly with SponsorBlock as a substitute before Vanced went down. But I noticed yesterday that it doesn't seem to support 60fps videos.
Browser with extensions is great and all but Youtube Revanced still way better option it support gesture google account (that google can't track you) picture in picture and it's easier on your device's ram/cpu, for in app ads you can try Lucky Patcher to remove ads as long as the app is not using account to buy premium features LP should work on most app
I would usually suggest Newpipe but that's a little buggy rn so Libretube is probably your best bet, that even has sponsorblock aka it skips in video promotions from influencers too!
I'd recommend NextDNS, although I haven't tried the AdGuard DNS. You can choose from many blocklists, add stuff to Denylist or Allowlist (which I had to do for AliExpresss app to work properly), check logs to see what was blocked or allowed, add Rewrites which was useful for lemmy.fmhy.ml and fmhy.ml, and there's a bunch of other protection options.
You can also test it out for free WITHOUT SIGNUP for 7 days. If you clear your cookies you can get another 7 days over and over without signup.
TrackerControl may work for this if you must use the stock app, newpipe is probably the best solution and finally, you can also use ad blocking dns and there may be VPN solutions as well.
Because the family premium tier gets you and designated family ad free YouTube when using Chromecast, and YouTube Music. Worth it for me. We're all cheapskates here, just some of us are less cheap!
