I've clicked through all the options in the settings and no matter what I click I can't seem to get YouTube videos to play in the boost app. Every time I click on one it opens my YouTube app and I don't know how to get that to stop happening. I'm on a galaxy s22 ultra if that helps.
Does newpipe not work for you? That's what I'd use if I didn't have a YouTube adfree subscription.
It would be cool if more people would host using peertube but it never seems to really get off the ground.
I'll be honest I've never heard of it until just now. But after reading about it I'm gonna give it a shot. I'm sick of youtubes bullshit.
