Hi everyone, I need some help finding the code for my pop-up form so I can fix an issue with the submit button. The button is showing up twice on the popup in Klaviyo (the one on the right side is the issue). I was told it might be a web-based problem. Can anyone provide me with some solutions to fix this issue? Thank you!

I’d like to suggest this idea if you want to remove submit button:

Step 1: Go to Online Store->Theme->Edit code
Step 2: Asset->/theme–critical.css->paste below code at the bottom of the file:

input[type="submit"] {
   display: none !important;
}

Hope my answer will help you.
