Using ios and OSX with files saved on Dropbox. I make a change in an excel file from iMac. Then I close the file completely from the iMac and close excel. Then I verify that excel is closed on ALL of my devices (iPhone X, two iPad Pros). Open the file from iPhone and the file that it opens doesn't have the latest change, and the phone excel says the file is open somewhere else but it isn't open on any of my other devices. I cant figure out what file it is actually opening, as it is not the current file on Dropbox.
I have been using Dropbox and Excel on this file for years and have never seen this before, and now it happens every other day. It is driving me MAD!!
