The official Gmail iOS app that debuted earlier this month in the App Store but was quickly removed on the same day due to a major bug that affected its push notifications feature has returned to the App Store today. Google had admitted the error via its Twitter account, apologizing and promising a fix.
Push notifications to mark the arrival of new emails were not working at all in version 1.0.1 with users seeing a “no valid ‘aps-environment’ entitlement string found for application” error upon opening the app.
The description of what’s new in version 1.0.2 of the app notes that you must uninstall the old version of the app or at least log out of your account (if you had managed to get the app before it was removed) before installing the updated version:
If you already have the Gmail app 1.0.1 released on 2 Nov, you will need to uninstall or log out of the old app prior to installing the new app.
