Be me, stop using primal. It's basically not even a real nostr client. Use your own node and self host everything and then you could just update your lightning address on your profile without relying on anyone else. Alby signer does have an annoying element that it uses a random npub until you import your own to the signer. Could always try nos2x. I would recommend amethyst client and amber signer on android. If you have an iPhone... You can use damus. I hear it's good. But If you were being me, you would dump that walled garden shit show for real open source software like android.
