   Description: We are investigating an issue where chat histories are not visible on Gemini Web (gemini.google.com) and the Gemini mobile apps on Wednesday, 2026-02-18 08:30 PST. Our engineering team has identified a background process that was causing the missing user conversation metadata and has successfully stopped the process to prevent further impact. Mitigation efforts are underway, and we do not have an ETA for completion at this time. We will provide an update by Thursday, 2026-02-19 09:00 PST with current details. We apologize to all who are affected by the disruption. Symptoms: * Users may find that their sidebar is empty or that previously saved conversations are missing. * Users may receive an empty response when attempting to list or search for existing conversations. * New conversations can still be 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.

5. resolved Feb 23, 2026, 01:20 AM UTC

   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.
