I accidently did this without splits. I tapped zap and while it was spinning I somehow swiped closed the wallet and the zap notification appeared but no zap was sent.
fake zaps are real

Must be a client UX thing. It’s the payment provider sends the zap receipt, not the client. Can confirm that this works fine with Amethyst when I zap from another client. I know some other clients fake the zap reaction because the lag time can be considerable. I prefer to see the lag because then I know it really went through.
