I second that, on how you keep it clean. I did optimum no rinse car wash in the garage, 5 minutes after pulling it out in the drive way it (black color) looked dirty again.
My bronco showed pending in the palsapp all the way even after dealer said it was delivered in Pennsylvania. Showed it was pending to New Castle, Delaware
My pixel 4 xl works flawlessly. I did have to reboot phone to get Android auto to connect the first time. Try restarting phone and deleting profile off bronco and having it find your phone again.
