It's something about how they have it configured. I have a '17 Honda Civic and its built-in CarPlay lets me pan and scroll just fine. However, on my '23 Ascent, I have to tap arrows to pan the map, and vertical "scrolling" is actually just pagination. Same iPhone, different behavior. It must be some simple config toggle on Subaru's end that they left off for whatever reason.
i believe it is related to the capabilities of the touch screen itself. something like "if no multi-touch available, fall back to the pan/scroll interface" makes sense to me.
