After a serious bug with the Google My Business App for iOS that started mid-last week, the new updated version is now available for download in the Apple App iTunes Store.
Google submitted the fix before the weekend after removing it from the app store. Now, the fix was approved by Apple and it is available for download.
The new features include the ability to quickly set your business hours for special days like events or holidays. As well as better manage permanently closed and reopen businesses via the app. The other features include a drag-and-drop menu to change your primary business category and phone number, a quick and easy way to mark whether or not your business is permanently closed and new support for landscape mode in the app.
