Yes: I absolutely understood the catalyst, but not the reason. I will rephrase my question: why did you want to switch? Is that less confusing? The person I am responding to seemed eager to leave Google Maps, but couldn't because of one critical feature; once that critical feature was there, removing the reason they had not to switch... but, there still had to be some remaining reason why the person switched: a reason that had caused them to be waiting to switch this whole time (and while I have some ideas as to what that reason might be, it isn't at all obvious which one and I didn't want to bias the answer by suggesting any). Is this really such a strange concept? :(
