If you changed keys, then yes, but if you kept the same key and use the same mints, then no. I'll be honest I'm not super familiar with Cashu wallets Nutzaps. I don't use them all that much.

You don't have a Lightning address on your profile right now so no one can Zap you.
Try adding your npub@npub.cash back to your profile.
It automatically changed my public key via my verified username but it kept secrete key so i still have access to my old post im just so confused if i still have access to both old keys shouldn't i be able to access the old setup?
Your public key should always be the same. When you go to wallet in Iris do you see your sats in the wallet? If not you may have to re-add your previous mints.
