If you’re looking to try another LNURL wallet, my go-to is nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm with the browser extension that supports signing events for desktop #nostr clients. You can import it into nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5 to spin up a quick mobile wallet as well.

The reason wallets like Breez and Phoenix don’t support it is due to not having any connection to a webserver to provide the address and automate the creation of invoices. LNURL is either a custodial wallet feature or you have to run your own node and set one up yourself.
