Our app requires jQuery. If you’re sure jQuery isn’t being loaded, you can add this script in your theme.liquid file after the <head> tag.
<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
You can test if your store has jQuery and what version you are using by entering this info in the google chrome console.
Go to your live store > Right Click > Inspect
Click console in google chrome
Add this code to the console
$.fn.jquery
// If there is concern that there may be multiple implementations of `$` then:
jQuery.fn.jquery
Our app will work with any jQuery version higher then 1.9
