Yep, same here. IIRC it fails because it's expecting me to enter a custom package name, but then there's no field at all to enter a package name. I've gone thru the settings multiple times and couldn't find that option so I too gave up.

Anyways, NewPipe works well enough for me, and if there's some issue I could always load it in a browser.

This isn't me trying to sound like a dick. But did you enable the option for it to rename itself? I can't remember where it is, but it's something along those lines.
