What Nostr client you use doesn’t affect your ability to receive zaps. Also, there’s no way to receive zaps to a Phoenix wallet. When sending zaps doesn’t work, the problem is more likely a temporary problem with the LNURL provider such as Alby. Nostr clients could do a better job at letting you know what went wrong, but it’s difficult cause a lot of things can go wrong and the LNURL provider doesn’t always let the Nostr client know what went wrong.
