Thank you for getting back to me and confirming that information. I believe the app you’re using that has added the coding is causing this issue. When I tried to add a product to cart it actually didn’t finish loading at all. It was spinning for 10 minutes. When I entered your website it loaded at a normal speed, so I don’t think it’s the amount of videos you have added but the coding specifically that is causing the issues.
If you go to the Section Store app page you will find a support button on the left hand side that looks like this:
You can reach out to their support team there and they should be able to help you with this.
