Wallet chain code issue

Hey, I created my wallet during the DevNet phase and was told at the time that I could use it on Mainnet. However, now when I try to import the master public key into the Mainnet wallet, it asks for a chain code — which I was never given.

Is there any way to recover or bypass this, or should I generate a new wallet for Mainnet instead?

you could probably use the original with some digging, but I’d just generate a new wallet
