I can no longer tell I have liked any particular HA or not because users I have clicked their grey heart pink days ago, those hearts are still pink.

Google Chrome OS and Google Chrome Browser.

i've got the same thing happening too. some are even pink that i'm not sure i've even clicked in the first place. i'm using firefox

Same for me on Chrome

I'm having this problem on Google Chrome as well. It would be really nice if this worked properly.

Yep, happening here too. Ever since the likes were "fixed" they've been staying pink. And not just the ones I've liked since that point. I suspect that every single avatar I've ever liked in the history of the existence of the like button are now pink. I'm on Firefox.
