When in "plan view" mode, the carplay home screen is missing the red arrow

Steps to reproduce:

Before you connect to the car, make a plan (put in a destination and press plan).

Connect to the car

Don’t open ABRP on the car.

Press the home button in the bottom right of carplay so you get to the home screen (not the one with the apps, the one with navigation and music).

Expected result:

This could be one of two, depending on what you want. Either a bunch of information about the plan, or the normal screen (tiny map with car position as a red arrow)

Observed Result:

It shows a little map, but with no arrow showing the car’s position. (it is centred correctly and moves with me, just missing the overlaid arrow)
