Every so often, YouTube changes something on their site that causes NewPipe to stop working. Usually within a few days, NewPipe pushes an update that fixes this, and we're back in business. Every time this happens, I donate to their Liberapay. https://newpipe.net/donate/
NewPipe has a few features that I like, but let's be real: most people use NewPipe for the 'privacy' feature AKA: blocking ads. At the risk of being downvoted for having an unpopular opinion: but if circumventing ads is your goal, then just get Youtube Premium in instead of paying for piracy. Because contrary to popular belief, the majority of that subscription fee is actually distributed amongst the content creators…
I am not paying for piracy, I am paying for an app that makes YT experience somewhat bearable, and lack of ads is only one aspect of it.
If you want to support your favorite creators, do it through different channels than by feeding the corporate beast.
