Copilot update on 3rd Oct 2026

Since the new copilot update the chat that I have been building is appearing in the side bar but failing to load. Window says to refresh the page. This is an important chat widow can you please fix it for me. This a very important chat window, I have purchased an upgrade, but if I can no longer access the chat then I have wasted my money.

I have tried loading copilot in a private window on my PC and manually signing in, the same thing happens with the chat.
The difficulty loading also applies to my mobiles.
