I have the 10.5 inch iPad Pro and these apps seem to be working for me still (and yes, I downloaded the Office apps right when I got my iPad and also updated when the new updates came on June 15). I haven't really used Word in the past on my old iPad (I had the iPad 2 before this) so I can't tell for sure, but I'm able to open Word, type out a document and save it on my iPad or iCloud or wherever + send copies via e-mail so it seems to be working.
