Hi Brody,

Thanks for reaching out to us. It should be possible to fix this with the custom CSS code. 

You can try this one - 

@media only screen and (max-width: 548px) {
  .amelia-v2-booking.am-dialog-el .el-dialog {
    margin-top: 0px !important;
  }
  .amelia-v2-booking #amelia-container .am-dialog-el__main-container {
    max-height: calc(100vh - 68px) !important;
  }
}

Custom code needs to be applied to the page where the booking form is. Depending on what you're using (Gutenberg blocks, or some page builder), adding the CSS or JS can be done in a few different ways. 

If you need help with adding custom CSS to the page, please take a look at this article.

Please, let me know if it works. 

You are welcome, Brody.

I'm glad that I could help.

If you have any other questions, please open a new ticket and we will gladly help you there.

Have a nice day!
