Sudden Document Reversion and Missing History

Hi everyone,

Today, I encountered a strange issue. When I refreshed a page, I found that my documents had reverted to an older version. Additionally, there seems to be a 5-day gap in my document history—those days are completely missing.

To clarify, I am not using the self-hosted version; this is occurring on the hosted version provided by Grist.

Has anyone experienced something similar? Could there be a specific reason for this, or might it be a bug? Any insights or solutions would be greatly appreciated.

Thanks in advance!
