"Feed not found in this channel." for any YouTube feed #28
Description
Tried adding different YT feeds, but keep getting "Feed not found in this channel." when running the 'check' command with the URL. Even the example in the docs (https://www.youtube.com/feeds/videos.xml?channel_id=UC8hQBcgwkZiG-cqhE1TDvzA) does not work.
