Seems like Piped and Invidious are both on their last legs. Public instances on both services are pretty iffy, they go down fairly often now. Freetube works well on desktop but no real way to sync subscriptions and watch history to a phone. Self-hosting Piped/Invidious might be the solution but I don’t know if it’s worth the upkeep when YouTube is actively fighting against it.
What adblock’s are you using?
uBlock Origin is the one that used to be relevant, but their anti-ad-blocking pop-up has made the site unusable for me lately.
I’m sure uBO will eventually work again but for now, no dice.
Ok, then I guess my location is not being targeted yet. uBlockOrigin with NoScript works well for me. There where a couple of slipups about a month ago, but hitting F5 would usually be enough.
