Bravepipe (a fork of Newpipe) is another alternative, which you can also use with Bitchute, Rumble and others. I have tried it and like it so far. I have it setup to do updates in Obtainium. I don’t have my Brax3 yet, hopefully shipping this week, and this is on a Pixel 9 with GrapheneOS, but I am sure you could do the same setup on Brax3. I had problems with Newpipe a few months ago when I first tried it and uninstalled it then as a result. Then found this a couple weeks ago.
About Bravepipe: “Due to restrictive project policy, the NewPipeTeam refuses to add platforms that they find offensive. This fork (BravePipe) will not be as restrictive. As long as the platforms work in the spirit of free speech, they could be integrated.”
