We are currently investigating an issue with Vena 365 Reports and Templates. Our investigation leads us to believe that Microsoft has made a change to how the "Unprotect Sheet" functionality works, and we are working diligently in partnership with them to resolve this issue. Not all users in your tenant will be impacted, as Microsoft rolls out changes gradually across their Excel user base. Our support teams are engaged and we will keep you updated on our progress.

Update – Microsoft has made meaningful progress in its investigation and has narrowed the scope of the issue to a recent change within the Microsoft platform. Microsoft engineering teams continue to investigate the issue and, as part of their response, have begun rolling back the recent change while they complete their investigation. As the rollback propagates through Microsoft's service, we expect affected customers to begin seeing the issue resolve throughout the day, although recovery times may vary depending on when the rollback reaches your environment. We remain in close contact with Microsoft and are actively monitoring the rollout across affected customers. We understand the disruption this has caused and appreciate your patience as Microsoft completes the rollback. We will provide another update as more information becomes available.

Monitoring - Microsoft has confirmed that the rollback is now fully deployed across their global network. While many users will start to see the issue resolve immediately, it may take up to 4 hours for regional internet caches to fully refresh worldwide. If you are still experiencing the issue, you can try clearing your Excel cache and restarting Excel to force the update locally. Please note that due to upstream network caches, this may not immediately resolve the problem for everyone, but we are continuing to monitor the situation closely. For step-by-step instructions on clearing office cache, please refer to the following: [Microsoft Support Guide for Windows](https://learn.microsoft.com/en-us/office/dev/add-ins/testing/clear-cache#clear-the-office-cache-on-windows) [Microsoft Support Guide for MacOS](https://learn.microsoft.com/en-us/office/dev/add-ins/testing/clear-cache#clear-the-office-cache-on-mac)
