Google said it was investigating the issue which is affecting some
users of its hugely popular cloud storage service.
The problem was first reported on 22 November by a user who said their
Drive had reset to a May 2023 version.
It is not known how many customers are affected, but people in multiple
countries have reported problems.
Drive is part of Google Workspace, a suite of applications which has
more than three billion users worldwide.
Users reacted angrily on Google's support site, with one calling it
"very devastating", adding "the files are very important to me".
