Are using Primal? Normally you can find it in your profile. This is your npub: npub1qyxlpj2gl6dt2nfvkl4yyrl6pr2hjkycrdh2dr5r42n7ktwn7pdqrdmu7u

It does not use your npub. I found the key I used in my amber logs. I've never seen it report a zap, so that may still be wrong but it accepted the format. It may also be that I'm a smaller account that doesn't get the volume of zaps of the bigger accounts so it just never announced one while I was in front of it.
