When the redirect.invidious.io instance gives user a link to "see directly on YouTube." it sometimes don't work.
For example in this link https://redirect.invidious.io/3ywlhRNX_Mc (random song) if you press any instance link it works fine but if you want to fallback in the youtube link it redirects you wrong, new url misses the "/watch?v=''" part.
idk if this is on purpose or a mistake, if somebody in the protect is comfortable with me looking forward it i would like to know.
