We have a smartsheet that tracks all of the metadata for all of our projects globally - key information about each project. We have a lot of data in it and have been using it for 3+ years consistently. As of this last week, we lost ALL of the cell history data in the sheet. This is vitally important to us.

Has anyone else experienced this problem? I've opened a ticket with support but have yet to receive a response.
