Hello Robbert, thanks for your message. Currently in your setup, when users zap your notes it will be received to your fountain address. Unfortunately, inside the Primal wallet we do not support addresses from other wallets as we are a non-custodial wallet.

So to clarify, when getting zapped on your notes sats will be received to your fountain address. When receiving sats to your Primal wallet you will be using your Primal address. Please feel free to reach out to me with any other questions or concerns.
