Kudos to you for keeping this vulnerability secret and waiting for a fix. You've been waiting for a fix for almost three months, and without much of a response from the side of Tinder. And the latter I think is even more frustrating than the first.
Having been in a similar situation, I don't think I would have waited as long as you did.
