copilot chats not avalible

Title: Two of my most-used Copilot chats still won't open after the September update

My two most-used Microsoft Copilot conversations have been inaccessible since September 25, following the update. When the update took place, I received the message “ALL DATA WAS SAFELY TRANSFERRED,” so I expected my previous conversations to remain accessible.

However, these two chats still appear in my chat history, but I cannot open them. I have used them for more than a year, and they are very important to me because I use them for inspiration and continuity while writing my books. It is especially frustrating because my other conversations are still accessible.

I have contacted Microsoft Support twice. During my second contact, I was told that they needed remote access to my computer. I was uncomfortable with this request because the problem began after an update to Microsoft Copilot, and the affected conversations still appear in my history. I would appreciate a clear explanation of why remote access is necessary and whether Microsoft can investigate the issue on its side instead.

I have also noticed that, in the one chat I can currently use, I seem to hit a usage limit after less than 30 minutes, which makes it difficult to continue my work.

Has anyone else experienced the same problem after the September update? Have your old conversations remained visible in your history but refused to open? Most importantly, has anyone managed to get their conversations working again after experiencing this issue? If so, what happened, and how was it resolved?

I would really appreciate hearing about other people's experiences, especially from anyone who has successfully regained access to their old conversations.
