On a new, out-of-the-box max pro M2 on Oreo, all the functionality provided by the in car entertainment system of the Tata Tiago XZ (updated to latest firmware at service center) was working fine. I only updated the default apps from the android play store to their latest versions. Next I started applying the system updates on the phone one by one and after each update checked that all functionality of the car entertainment system was working or not.
I can now confirm that after updating to Android 9.0 (Pie), I an not able to receive phone calls through the car entertainment system. The phone is paired with blue tooth and the car system is able to play music from phone, even fetch the call logs. However when there is an incoming phone call, there is no ringing of the car speakers, pressing the call receive/reject buttons on the steering wheel does nothing. This same issue also happened on my earlier phone the max pro M1.
