As noted by Google, the company's native Gmail app for iOS has returned to the App Store. The app debuted two weeks ago, but was quickly pulled after a bug breaking notifications was discovered as soon as users began installing the app.
Two weeks ago, we introduced our Gmail app for iOS. Unfortunately it contained a bug which broke notifications and displayed an error message, so we removed it from the App Store. We’ve fixed the bug and notifications are now working, and the app is back in the App Store.
Google notes that in addition to the notification bug fix, the company has also improved the handling of image HTML messages and has promised to continue "iterating rapidly" to bring new features to the app.
