Horizontal WIX forms - design bugs

I’d like to have a horizontal form on Wix Studio for collecting newsletter subscribers.

I’m able to put all of the elements in a row but the confirmation message only shows up underneath the submit button, so it looks really awkward as a horizontal form.

To have the message more legible, I have to make the subscribe button larger but this messes with the design.

WIX forms would be greatly improved if the confirmation message was independent of the confirmation message was independent of the subscribe button width.

To go around this I also tried having the form have multiple slides so that the confirmation message would take up the full page as the last slide, however, the Next button stays stuck on the right hand side on mobile and looks really awkward. Also, the Next button does not adapt its height to the height of the form feilds.

Please fix this!

Thanks,
a designer
