I believe it is the same with the sad face and it used to be with the wow too but pretty sure they changed the wow one. Not sure if they have the others. But they only get credit for likes, hearts, and I believe informatives and now wows I think? But not for sads or angries. Which stinks because most people use it because their sad or mad about the situation/for OP and not because they’re being mean but some misuse them. OH!!! And I forgot about the laugh emoji. That one counts too I believe. Even though people also misuse that.
All but the angry reaction count. Go here and play around with @PeaDawg's posts and you'll see.
