I’m sorry to hear that your previous Copilot chats and images are no longer appearing, especially after you have been using Copilot for several years.
Since you have already tested Chrome, Firefox, Incognito mode, and signed out and back in multiple times, please confirm that you are signing in with the exact same account and sign-in method originally used, such as Continue with Microsoft, Continue with Google, or Continue with Apple. Personal accounts and work or school accounts have separate chat histories.
If the correct account is being used and the issue continues, it may require further investigation by Microsoft Support. When contacting them, please provide screenshots showing the missing conversations and empty images, along with details about the account and sign-in method used.
Please note that this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas only.
Thank you for your understanding.
