Sort of random, but some videos stop about a minute in. The bug symbol appears at the top of my phone. Fix: close and reopen newpipe and all is good until it happens again. Bug reports a network error when this happens. Happened at home and work, two different networks.
Edit: ver 25.2 just updated this morning 03Aug23
It doesn’t seem to happen anymore. It updated for me on August 3rd. That might have been the fix
