Copilot cloud chat history not syncing on iPad

I’m signed into Copilot on my iPhone, MacBook, and iPad using the same Microsoft account and the same sign‑in method. My iPhone and MacBook both show my full cloud chat history, including my most recent conversations. My iPad shows the correct profile name and email, but it does not receive any cloud chat history. I have already reinstalled the app, rebooted the device, and signed in/out multiple times. Please reset or clear the Copilot identity token associated with my iPad so it can receive cloud chat history from the server. My other devices sync correctly, so this appears to be a device‑specific token issue. Thank you.
