A family of Microsoft word processing software products for creating web, email, and print documents.
Which operating system are you running on the tablet?
Do you have an Office subscription or just some basic version of Office with limited functionality?
Yes, I have a subscription. Just updated the app in the Play store about an hour ago, but the issue persists.
UPDATE: I had to use my computer's full version of Word to check the autocorrect options and remove the auto capitalization of "i" -- which, incidentally, is still annoying because now it won't auto capitalize if I actually want "I"... I tried adding "i[space]" into autocorrect instead, but it wouldn't accept it.
