But it is off. I leave it always off these days.
Strange, this is what I see when ext is off and I click Log in in top menu. https://image.nostr.build/6afa8e2817afe212efdfde0417c875c48de826f8a965b8b6e4c4252182e88e7b.png
It worked after reloading the page. Maybe it was cached. Did you announce nsec.app with NIP-89 as a handler for NIP-46 events?
Now I did. Don't see it here though https://nostrudel.ninja/#/signin/address/create
