I know that there are extensions that re-enable the dislike feature for YouTube. Do any work with YouTube Vanced?

I thought y'all knew tech

No idea

You're mixing things up

The extensions were developed for browsers

Youtube Vanced is an android app, you can't add extensions to it on your own like on PC, that's not how it works.

But he good news is that the Vanced developers will probably implement the functionality like they did with SponsorBlock:
