I currently use brave on iOS to block YouTube ads. Is there any other option right now? I’d be willing to switch.
If you don’t mind sideloading and refreshing the app from your PC every 7 days, I recommend (and use) uYou+ as a sideloaded app. It has PiP capabilities w/o needing premium, along with a built-in video downloader, sponsorblock, and adblock.
