Unable to Edit Documents in iPad OneDrive App

As a standalone app, OneDrive only allows for read only access.  Editing documents via the OneDrive app for the iPad requires that a licensed version of Microsoft Office also be installed on the device.  If the user does not have an Office Pro Plus subscription included in their Office 365 license, they will need to purchase an individual Office license or install another app capable of editing documents, such as QuickOffice.
