Blurb from app store on my iPad:
“Microsoft Office is now available on iPad: We're combining the Word, Excel, and
PowerPoint apps you know into a single, iPadOS-optimised app. Plus, you'll
see additional tools to keep you more productive than ever. For example,
you'll be able to quickly create and sign PDFs, and transform pictures into
documents.
Get to Image-based Workflows Readily: Tap 'Share' in the phone gallery
outside the Office app, to get to several actions like Create PPT, Create PDF
and more. In addition, if there are any recent screenshots when you open
the Office app, these are surfaced as a suggestion to covert to PDF or PPT.
Insert date, shape, image and notes in PDF: Now you can easily insert date,
shape, image and notes in PDFs using new capabilities.”
On devices with a screen less than 10.1 inches, all that’s required in order to perform edits is a free Microsoft account. But on larger screens, you’ll need a 365 subscription or account.
I tried the app on my 10.2 in iPad 8 and my 7.9 in iPad Mini & can attest to these requirements. Ergo, the app is on my iPad Mini but not on the big one.
