This has me stumped. On Android Auto I see a call come in and on the screen I have the green Answer / red Decline choice. But no matter what I do with the CX30 command dial, nothing happens. Pushing it doesn't answer the call, and rotating it does nothing on the screen. What is supposed to happen? It looks like Android Auto is expecting me to tap the screen, which of course can't be done in the Mazda. Am I missing something? I am using a Pixel 4.
