There are no ads on new pipe. It just has a stupid trending tab with crap that is confusing. Ignore it, this is not your feed. Go to subscriptions which is what we used to have before tech giants convinced us otherwise with curated content.

Seriously, NewPipe is what all apps should aim to be like.

I had the same experience, but hopping over to F-Droid from the Play Store provided a different NewPipe (instead of 'Newpipe') that I believe is the pertinent one.

I think you download a clone of new pipe.

There is no Newpipe on the Play store, it breaks the T&S of the play store.

Here is the official website for Newpipe https://newpipe.net/
