Additional file-related features and issues within Microsoft Teams for business
Further to my previous reply, I've just sent a document for review and been asked to move a paragraph above the table to which it referred, as well as to sort out the completely messed up paragraph numbering. The reviewer had been using the online application. I of course had been using the desktop version. When I asked the reviewer to switch to the desktop one, both problems went away.
It's this kind of thing that makes us unwilling to go near the online versions - we just can't trust them to show what's in the document and, if we try to use them to make changes, we may never get usable documents back.
Pushing us into the online versions in these circumstances does not seem very reasonable.
