why do some YouTube videos on lemmy have a thumbnail, while some don't? (lemmy.world)

If you go to !videos@lemmy.world and scroll you'll see some of the posts have a youtube thumbnail image, but not all.

I wanna post YouTube videos, but no one seems to engage much without a thumbnail, which makes sense, but I'm not sure what would result in the post actually having a thumbnail

If anyone has advice or guidance I'd appreciate it :) Thanks!

EDIT: so far it seems like it's potentially a combination of what version of lemmy the posters account is running, and how that instance is configured...

I can fetch the damn thumbnail just fine. I have to do it on every YT post I submit.

Reddit can fetch thumbnails from hundreds of websites, all of them different, including a bunch of porn sites. Pretty sure they have to code each site to map out the right URL and tags to parse.

I know Lemmy is OSS, but I really wish it wasn't so slow on the uptake with these things.
