A family of Microsoft word processing software products for creating web, email, and print documents.
I got it working right now (the steps you mentioned worked ok for me).
Only problem is...I can only open from the Google cloud-based drive, not the local copies of files I've put "available offline" a few minutes before.
Still looking for the local GDrive in my iPad (and YES, IT IS updated, and YES, apps are updated, too...).
