Ha! I think if you open up the profile editor in another client you should be able to fix the @ symbol in your handle. Unless you’re attached to it.

I don't see it that way in Amethyst. Amethyst is the "Bitcoin standard" of nostr clients IMO
I think it will work if you edit it in Damus. I just tested it. If you type an @ symbol before your “Username” it will show up as a double in some clients, so you should only enter a username without the symbol. The problem is that no two clients seem to follow the same specs for managing profile data.
