**Title :** Some customers may have experienced an issue with Gemini where conversation history may not have been visible. **Description :** The issue with Gemini has been resolved for all affected users as of Sunday, 2026-02-22 12:08 PST. Based on our initial analysis, the incident was caused by an internal job that caused some valid conversation metadata to be deleted, which resulted in the conversations from the side navigation to be hidden. Users could still access the hidden conversations requests and responses from the activity section. Our engineering team mitigated the impact by restoring the data from the appropriate backups. We thank you for your patience while we worked on resolving the issue. **Symptoms :** * Users may have found that their sidebar was empty or that previously saved conversations were missing. * Users may have received an empty response when attempting to list or search for existing conversations. * New conversations were still created and utilized normally. **Workaround :** * Impacted web users on gemini.google.com can navigate to Menu (top left) > Settings & Help > Activity. * Alternatively, users can navigate to myactivity.google.com/product/gemini to view their conversation history. * Mobile users could navigate to their profile (top right) and select Gemini Apps Activity.
