Goto your profile on Iris and edit. You will see a spot for the address or LNURL LUD-06 or LUD-16. They are the same. When you do let me know. Ill tell you if I can see it.

Also Iris has a great function in settings. Get a bunch of relays. 7 at least for mobile but if you like desktop/laptop 10-15. You can find good ones here https://nostr.watch/relays/find then in set them publicly so it goes to other clients. After that save your info. There will be an option for that. Iris has alot of good stuff.

also are you using a private key extension. They keep it safe from clients.
