You can just go on your previous notes, click on the “zaps” to see who zapped you, and for how much.
Same thing with comment reactions.
Ok the stat page helped me figure it where that large zap came from. See the View link (I really like this)
Thank you, nostr:npub1ppjkfvk0ek3g584gp7qp9d3znwdznadchet7q2aez9r27620n9zs45xvx2 :D

Am I doing this wrong? When I click the zaps, I can send myself zaps.
Dont zap yourself. Click here: 
This is all I see:
Are you on primal?
Different client.
I might suggest trying other clients out as well. Damus if you have an iphone.
Nostrudel.ninja for desktop.
Satellite.earth for desktop.
Many many others..
Also: nostrnests.com
For audio rooms. (Like twitter spaces)
I switch through a few. Primal I can't do anything on with my laptop(?), so I use Iris. I also check out nostrudel, satellite, and just now found nostr.band (i really like their stat list). I am using a cheap walmart laptop and an android phone. Nothing fancy here.
Cool. All good.
You have to go back and open your own note up. Then click where I showed you.
