You go to the subscriptions page? I've been subscribed to channel RSS feeds for a year or so now, never even go to YouTube to "browse" because the interface is so awful.

I'd like to figure out how to filter Shorts from my RSS feeds, but my preferred channels almost never use them so it hasn't been a big deal. The only other annoyance is live streams, which seem to debut on my RSS feed several hours before they're actually live (with no clear information about the "live-iness" of the video).
