No worries, a lot of anime fans from recent years wouldn't know as it feels like it happened a generation ago. I had to double check when that partnership occurred and it was September 2016, so that was a couple of months after Anime Limited last acquired a bunch of Crunchyroll titles. Some did survive like Konosuba, Re:ZERO, Rokka, Testament of Sister New Devil, and Twin Star Exorcists which were mainly dubbed by different studios than Funimation (that being said I think Mob Psycho was also dubbed by a different studio).
