I want to like NewPipe but I've always had problems with resuming videos after pausing them in the background. Most of the time my progress is just completely lost. Also, full screen and popover mode have been broken since Android 12. I use Vanced at this point.

Resuming issues were bug in the last few versions, but has been fixed in the latest release.

Still broken for me, and I've used the thing for years - very familiar with the quirks.

Also a long time user, but the issues described were only the last few months for me. Perhaps there are device specific bugs. I just rolled back to an earlier version until they were remedied
