Thank you for sharing this with us. The issue about the viewport not being set to “device-width” is a bug with Google.
As for the other two issues mentioned, those are relatively subjective. It’s difficult for a computer to tell what is or isn’t too small or too close together, because it doesn’t understand the context the same way a human does. We believe the websites are very easy to use on mobile devices and have tested them thoroughly to ensure they’re easy to navigate without tapping on the wrong element.
