Word files saved in iPad cannot be attached to email app
My wife is a school teacher and lot of her work involves working on word files and school's email. Microsoft word on iPad saves the documents in folder named iPad. However, when she opens the mail app and wants to attach the document she cannot find it! Because when you press add attachment it opens iCloud drive. Also when she wants to save the word document in iCloud drive it does not show while saving. Currently she has send the mail to another account, open in macbook (which is mine with different iCloud account) , then send it from there.
Anybody can help with this?
Either the word app should be able to save the docs in iCloud drive or the email app should be able to access the iPad storage.
Need help for this.
iPad Pro 9.7-inch WiFi, iOS 10.2.1
