Thanks for your concern, Primal wallet is custodial and has nothing to do with NWC there is only Alby providing NWC connection with clients and it is done speeratley between client version whether desktop or web. So, the best solution for you is to connect your nwc or webLN for the web and do the samething for the mobile app. Because this process includes sensitive informations from the user side so we can’t hold it in any place until it is connected from the user himself. Sorry for the inconvenience, Primal wallet is dedicated for Primal only as far as we know.
