I create a word document in Microsoft Office then save to a folder in Dropbox. On retrieving the document I discover it’s a blank page. I’ve powered down, deleted app then reinstalled it, as suggested by Apple support but to no avail. Is it because Microsoft want me to take out a subscription as I had this free version of Office for years or does the problem lie with Dropbox? I’ve been using Dropbox without any issues for the past 5+ years
