Hi, LeoniE withanE
Sorry for this frustration. Since Firefox and Incognito show the same problem, I wouldn’t ask you to repeat those browser checks.
Here are some suggestions you can try:
First, try exporting your saved conversations outside Copilot. Open your Microsoft account’s privacy dashboard, then select Privacy > Empower your productivity > Copilot > Your Copilot app activity history > Copilot apps > Export all activity history. This downloads a CSV file you can open in Excel to check for missing conversations. Choose Export, not Delete. This is a way to retrieve available records, not a guaranteed fix for the missing history display.
If the export is also missing your conversations, use the Privacy support and requests page to contact the Microsoft privacy team about accessing your personal data. That route is available when the dashboard hasn’t addressed your request. Include the date everything disappeared, screenshots of the empty images, and your existing support case number privately. Ask whether the missing content is still retained and accessible, rather than requesting another browser reset.
