Don't sign up for multi-month, it's useless
I'm a paying member (male). The first few weeks to a month were actually pretty great. I had many matches and went on a number of dates. Then after that initial period, basically 0 matches-- completely dry. The same type of people that matched previously no longer matches. The only people that I get any likes from are completely not my type (and they can tell my type based on who I matched with!).
What I'm guessing is that they prioritize new paying members early on (maybe to maximize positive reviews, minimize complaints and refunds, etc), then basically forget about them. Your likes may not even see you after that.
Btw, this is not just CMB, same thing is happening on another popular app that I'm on. Very annoying.
EDIT: Since they won't let me post over there, Hinge is the other offender. Same thing, successful early on, completely dry after the first few weeks. And boo to you Hinge for censoring.
