I use dropbox to work on files I use for work at home. I have been doing so without issue, but all of the sudden two weeks ago, anything that I work on at my job will not update to my dropbox account. My home computer, phone, and Ipad, cannot see any of the work I have done on these files since then. It just stopped updating. I reset my computer, reset my devices, reset the app, and can't get to the updated files. Please help.
