Dear, Morten1976.
Thanks for your seeking my proposals.
I understand how debilitating a site-wide error can be, especially one that affects the functionality and user experience of different devices. Your description of the JQuery error on your Magento2 site indicates to me that you require an experienced developer, just like myself, who has a deep understanding of both JQuery and Magento2 ecosystems.
In the 10 years I have been in the industry, I have worked with various front-end and back-end technologies – including HTML5/CSS3, JavaScript/jQuery, PHP, and Magento 1 & 2. And from your project's profile, this is exactly what you need.
Moreover, my adeptness in troubleshooting and problem-solving will be crucial in identifying and addressing the underlying cause of the issue affecting your product attributes to display only on desktop devices. With me on board, you can trust that your site will become functional for all devices once again while ensuring a seamless user experience. Let’s fix this error together!
