I'm using Swipe Pages and the Insignal script won't work unless it's AMP compliant.

¿Insignal, could you please consider making the script AMP compliant?

This is what a third party provider (Swipe Pages) answered when asked how to implement the Script.

****
<script async src="https://app.insignal.co/pixel/EM5DwfGpDkqbtldg"></script>

The code above is normal JavaScript code. AMP has a lot of restriction and will not allow you to add JavaScript code. AMP's js looks like this as mentioned below

<amp-script src="http://example.com/my-script.js" width="300" height="100">
<p>A single line of text</p>
</amp-script>

Unless the third party provider which is insignal in your case provides you an AMP compatible code, you can't use it. So I suggest you to use our standard page.

Still you get 5 Tacos, cause the product works.
