You have an on-chain address in your profile when it should be a LNURL. 😉
Damus should probably handle this... at least you can copy it with the wallet selector

Muun is set to lightning network as my receiving protocol 🤔
I knew 100% you were using Muun! Lightning invoices are different from LNURLs, and Muun doesn’t support them. Try Wallet of Satoshi. Go to Receive > Lightning Address and grab the LNURL under the QR code or the Lightning Address that looks like a funny email.
Done
🤙
Or use Albee to get a custom ln address.
