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.
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.
