It’s two things on YouTube. Certain videos (seems to not occur for super popular videos) dont load. Just a white browser screen and black area for the video, but no video, suggested videos, or text at all. The second is searching. Certain terms that seem unremarkable and unrelated will leave out the channels I’m after. Eg. “Cop body cam videos” will only suggest videos from 1-3 channels, or “Hardcore WoW clips” won’t include the channel I’m after (the most obvious and largest for this search). Using Brave or Chrome produces the expected/desired behavior (but isn’t fixed with some other browsers or local YouTube clients).
