Hello, I have Pages 5.2.2 on OS X Yosemite Public Beta 3. I upgraded my iCloud account to iCloud Drive while updating OS X. With Pages I cannot open the documents from iCloud Drive. Even if I create a new one, edit it and close it, I cannot reopen it. I just have an error "Impossible d'ouvrir le fichier". From iCloud.com I am able to open all my Pages files, both old and new. From Pages 2.4.2 on iOS 8 it works too. Is this a known issue? Is there a fix? Thank you!
