Tire pressure indicator in iOS app not calibrated to tire size

[Watchesandburgers]

The tire pressure spec’s for my ‘22 GTS are 41 psi front, 45 psi rear, as indicated on the driver’s door sill. However, the iOS app shows different recommended pressures. I imagine this is because the app doesn’t know that I have 21” wheels versus the stock 20” wheels. Nothing I can do about it, but.. c’mon, Porsche!

You can set the wheel and tyre type in the PCM on my UK spec car.
I change it between 21" summer and 20" winter twice per year.

It's set properly in the car. Just doesn't carry over to the iOS app. Does it appear this way for others as well?
