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

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.
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.
