Ask HN: Why Tinder is so terrible of an app?

As a somewhat recent user of Tinder I can't help but wonder how extremely popular app like Tinder can be so badly made? I use Android so I can't speak for iOS but it feels like it was built hastily by bunch of junior developers with complete lack of regard for quality.

Okey some UI mistakes here and there sure, not a big deal. However for an app like Tinder I'd assume that there was a throughout testing for errors due to internationalization. In my language at least there is one glaring error in the spelling or at least it reads very weirdly.

But what really bothers me and contributed me to submit this question is that I recently or well I think it has been ongoing for a while is a bug that stops me from changing my personal information. Like really, this is the level of quality I can expect? Contacting the customer support was no help either and they haven't responded in 3 working days since I last sent an email.

I am astonished and wonder what could have led to this, is there a serious lack of experienced developers in the team? Is the culture terrible inside Tinder? No one admits mistakes and there is a lot of defensive coding? I'd love to hear from someone who knows the inner workings of Tinder and why its current state is what it is.
