It's an unbelievable UI oversight to me that the platform gives zero feedback on whether or not you've "liked" someone's community post or screenshot before or not. You click "like", the like counter goes up by one, but the button remains the same grey as before. Weeks later you might encounter the same post, and you'd click "like" and instead the counter drops, telling you you had it liked before.

This is silly, just turn the thumbs up logo green or something when you've liked the post already.
