Copilot chat titles visible but conversation contents missing across all devices

Merci pour votre aide, mais je tiens à exprimer ma plus vive insatisfaction concernant le service client de Microsoft. J'ai ouvert quatre tickets via la section « Obtenir de l'aide », et je n'ai reçu que des promesses d'assistance rapide, des escalades vers des services supérieurs et même la promesse d'un appel téléphonique. Il a été clairement établi que tout est correct de mon côté et que je n'ai commis aucune erreur. Ce problème doit être traité par les ingénieurs et développeurs de Copilot pour synchroniser leurs serveurs. Il est totalement inacceptable qu'après quatre tickets, absolument rien n'ait été fait. Évidemment, je partagerai publiquement cette expérience — pourtant bien réelle — et je ne passerai certainement pas à la version professionnelle de Copilot comme j'avais l'intention de le faire.

Thanks for trying to help...

However, I want to express my deep dissatisfaction with Microsoft Customer Support. I have opened four different tickets via the "Get Help" section, receiving nothing but promises of quick help, escalations to higher-level teams, and even a promised phone call. We have already established that everything is correct on my side and that I did nothing wrong. This issue requires Copilot’s engineers and developers to investigate and sync their servers. It is completely unacceptable that after four tickets, absolutely nothing has been done to resolve the issue.

I will certainly share this truthful experience publicly, and I will definitely not upgrade to the professional version of Copilot as I had previously intended.

Hello JB

Thank you for reaching out. I understand how concerning it can be when your previous Copilot conversations are visible in the chat history, but the conversation content does not load.

Before contacting Microsoft Support, I would recommend trying the following basic troubleshooting steps:

• Sign out of Copilot completely, close all browser windows, then sign back in with the same Microsoft account.
• Open Copilot in an InPrivate/Incognito browser session and check whether the affected conversations load.
• Clear your browser's cache and cookies, then try accessing the conversations again.
• Test using a different supported browser such as Microsoft Edge, Google Chrome, or Firefox.
• Verify that your Microsoft account is the same account used when the original conversations were created.
• Check whether the conversations are accessible from another device, such as a mobile device or a different computer.
• Ensure that both your browser and the Copilot application (if applicable) are updated to the latest version.

If newly created chats can be opened normally but older conversations continue to appear blank after completing the steps above, the issue may require further insights from Microsoft Support since we Moderator do not have any tools nor direct access to Copilot to review, recover, adjust or update your chat history, please reach out by:

• Go to Contact Us - Microsoft Support 
• Select Copilot
• Click Get Home Support
• Type a brief description of your issue in the search box.
• Click Get Help and select Contact Support below. 
• Go to the Products and services tab and choose the appropriate product.
• On the Category tab, choose the appropriate category or an alternative option.
• Go to Confirm. Look for and select "Chat with a support agent in your web browser" (during business hours) if available. Explain your situation clearly.

I hope this helps, and please let us know the results
