maps.google.com never works for me on the iPad - whether I'm using Safari or another browser.
From what I've been reading, everyone who has a current Google account will be fine using exchange to sync with Google. It's only new accounts that will miss out on EAS.
Google have already paid for us to use it so we're already licenced.
So it doesn't matter if I buy a new WP8 phone and setup my existing email account?
I tried to use Google Maps in Safari before the app and it was buggy as ****, I could never make it work properly. In fact the new Google Maps app isn't exactly much better in all honesty. It looks better but I wouldn't rely on it because it's still very buggy.
I never really had a problem with either in iOS! Maybe an issue with your device?
Ah, so I guess Google admits they were doing this as they say there will be a fix "soon". Gotta love the Google/Microsoft ecosystem wars.
