Google Drive users are reporting that recent files stored in the cloud have suddenly disappeared, with the cloud service reverting to a storage snapshot as it was around April-May 2023
If you're affected, the best action is to not change your Google cloud storage, particularly the root/data folder until this is resolved, instead open a support ticket with Google. If you have room, copy your app data folder to a local hard drive. Google Drive tier one support appears to be volunteers, which means the ticket is needed to escalate to the paid support engineers. Take a look at where you're using non-enterprise cloud services to store enterprise data and revisit the backup and recovery processes for those to make sure that you're not needlessly risking data loss.
