Microsoft also notes that the primary URL for the updated Copilot experience is changing to Microsoft CoPilot
If you decide to use an app instead, Microsoft also officially supports Copilot on iOS.
I'd also make sure you're signed in with the same Microsoft account that contains your existing conversations.
