I am an idiot, but...

I have a 2019 Jeep Cherokee.  I plug my brand new, updated, registered MS906 into the OBDII port and the MS906 can't read/ determine the VIN.  Weird, but ok.  I input manually and scanner tells me I need to use a 12+8 Chrysler adapter instead.  This entails removing the radio knob panel, the surround of the screen, the screen, remove the ports from the back of the radio panel and screen and plug them into the adapters (2).  If I was doing this on a job that would be fine but I also intend to use this scanner to help when purchasing a used car.  No one is going to let me remove their dashboard panels and components to connect.

Why can't this (sophisticated) system access the diagnostics using the OBDII port as designed?  What am I missing?

Thank you for the clarification.  Do you know if I'll have a similar issue when connecting to a Land Rover?

Scanner is brand new 3 days old.  Updated via wifi - 40 updates.  Do I also need a subscription or is that included for the first year?
