App freezes on phone whenever wi-fi isn't enabled (even if connected via USB). "Android Auto needs Wi-Fi" error message cannot be dismissed as the Cancel/Settings buttons do nothing and no other apps can then be accessed (even Send Feedback!). You have to wait for it to present the "App has frozen" message then close it. Also I continually get the "Phone not ready" message when I try to make a call, especially if Google Maps is being used. An absolute disaster in reliability terms that causes you to take your eyes off the road far too often.
