Using BETA version iCloud on a PC, logged in as myself. When I send a copy of the pages file to my iPad from the BATA version the file will not open. I have tested both the iPhone and iPad, updated the IOS and re-installed Pages App. When I send page files between the iPhone and the iPad no issues as before, I just have the issue now when using this BETA version iCloud on the PC using Google Chrome.
iPhone 5c, iOS 8.1.3, Accessing the iCloud Pages App (PC)
