Hi guys, I'm trying the official Gmail app to replace the stock Mail in iPhone 5, iOS 7. I read in macrumors forum that we can't change the sound of new mail. I can try to live with that. One thing that I can't live is: I never heard any single new email notification from this app. Notification center setting for gmail: - alert style: Banners. - Badge app icon: on. - Sounds: on. - Show in notif center: off - Show on lock screen: off. Help please guys.
