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.

I thought I was going crazy! This happened to me yesterday all day and only today once.
