Awesome speeds, but a lot of YouTube buffering.

I got Starlink about a month ago and everything is going great with my download/upload speeds and latency when gaming. I get around 300mbps download and 50 upload, but the problem I have is with YouTube. Videos won't load up quickly and I get a lot of buffering (watching livesteams on 1080p is very difficult). I tried other streaming platforms like Twitch and Netflix, and everything is working fine there. Does someone have any idea why this is happening?
