I believe the one thing i see lacking for newpipe is viewing livestreams. Revanced is the way to go for a good youtube experience, but i use newpipe for downloading and saving a video offline.
This is a live stream I just watched to check that it works https://www.youtube.com/watch?v=ydYDqZQpim8
It's a water pool in the Namib desert, so safe for work
There were times in the past where this was not the case, but it was likely 0.24 or before.
