Hello,
1. Replace the form structure with the one below:
<div class="row wd-spacing-10">
<p class="col">
<input type="email" name="EMAIL" placeholder="Your email address" required />
</p>
<p class="col-auto">
<input type="submit" value="Sign up"/>
</p>
</div>
To hide the white area, add a negative margin to the last section in the page builder.
2. Make sure that the portfolio page is created and assigned here – https://prnt.sc/SqpZLDXp3f4M
3. That https://prnt.sc/jG73tLUzE15B shortcode is related to the WPB page builder, it cannot work with Elementor.
Kind Regards
.
