What client are you using?
I'm on #amethyst.
Try this: 👀 Long press on the zap icon instead of tapping it. You'll see a pop up where you can set your custom amounts.
That worked, thanks for your help!!
You should be able to change default settings somewhere. So you dont accidentally fast zap to much.
You can add several defaults or quick zaps if you long press the zap icon. You can also link NWC if your wallet supports that for instant one tap to zap. Lastly, if you want to send something that isn't one of your defaults, you can double tap the ⚡.
