Among other features, the app improves on the experience of using Gmail through the standard iOS email client by supporting push notifications.
In order to enable push notifications in the default client you have to use a workaround which involves setting it up as an Exchange Server.
Push notification allows an email server to send out data on its own schedule, rather than waiting until a client requests it.
An explanation of the app's problems on the company blog doesn't go into detail or give a time table for a planned fix. It reads:
Earlier today we launched a new Gmail app for iOS. Unfortunately, it contained a bug which broke notifications and caused users to see an error message when first opening the app. We?ve removed the app while we correct the problem, and we?re working to bring you a new version soon. Everyone who?s already installed the app can continue to use it.
According to TechCrunch, the problems include push notification not working and a lack of support for multiple accounts.
