I haven’t caught to that one yet - Tradução em português

Hi everyone!
Qual a tradução de " I haven’t caught to that one yet"
é um diálogo e o cara termina com essa frase. Porém não entendi o contexto.
Segue o diálogo:
Abidemi: Interesting. Interesting. Maybe a bit like in Japan – back to Japan again, where they have mayonnaise on their pizza. And at the beginning for me too it was very strange when I first tried it. But now, I think from that experience, I’ve grown used to put in mayonnaise on my pizza, and actually love it.

Rory: Okay, yeah. I haven’t caught to that one yet.

Muito obrigada.
