I have an old file, which was created in 2017. This file has been in my dropbox since then and was not changed until today. Today, by accident, I've overwritten that version with some unintended changes to the file. I immediately tried to recover the old version of the file, but the 2017 version is not available.
I have a Free Plan. From my understanding, Dropbox has always been able to restore files to the previous version, regardless of when it was last saved (in this case, in 2017), as long as the current change was made within the last 30 days. If a change was made more than 30 days ago, then, the old version would be lost.
Since the only change was made today, why can't I recover this file any more? Has something changed in the way Dropbox works?
Thank you for your help!
