InDesign Not Saving Over a Months Work
We created an InDesign file on September 13 for our publication. This file is saved on Google Drive with gigs of space still available. We have done several weeks worth of work on this file. And manually saved the work everyday.
Today, opening the file shows none of the saved changes. It shows the September 13 date as last modified. We are horrified.
What could possibly be going wrong?
We are using InDesign version 31.1 on a new iMac that was running High Sierra at the time. It now has Mojave on it.
Please advise.
