Feature Description

m.youtube.com is not on the supported links list for PipePipe. As a result, no links served from m.youtube.com will be opened in PipePipe by default. I would think this would be a sensible change to make, and it may be worth looking at the YouTube app's supported links to see if any others are missing.
