The embedded form appears cut off on mobile because there's an existing CSS codes in your website that limits the iframe height element when viewed on mobile.
I suggest to re-embed your form using iframe embed code and then insert min-height:2722px !important; on the style attribute found on the iframe embed code.
<iframe onload="window.parent.scrollTo(0,0)" src="https://form.jotformeu.com/form/61153700236344" allowtransparency="true" frameborder="0" name="61153700236344" id="61153700236344" style="width: 100%;border: none;height: 2722px;min-height: 2722px !important;" scrolling="no"></iframe>
