We have identified a critical issue in our Google SecOps environment. All data in the Advanced Dashboard for the entire month of January is missing. This issue affects every dashboard view, regardless of the dashboard type.
We have already opened a support case, but there has been no update or response so far.
This situation is impacting our reporting and visibility for January 2026.
Has anyone experienced a similar issue before?
If so, could you please advise on possible causes or troubleshooting steps?
