Not OP but yeah, it tends to take a day or two after the API break for the devs to put out a new release.
Of course this is understandable though! YouTube is the one breaking the API and the devs react really quickly which is great.
I use the version from the github page. They are updated much faster. So when I realized something broke there is usually already a fixed version up on github.
And the GitHub version warn when there is a new version
Yes. I'm not sure what I've done wrong but I tried three times or so the last year and never got off the ground with using newpipe, always broken.
