If you find that users cannot click on any links, buttons or other elements of your store, it most likely is related to a third party app conflict.
When third-party apps are installed on your storefront, the app will add in its own custom code. Sometimes, this additional code can conflict with the theme's native code which can results in functionality and layout issues.
If you're looking to install third-party apps or custom code, we suggest getting in touch with the app developer or a Shopify Expert who would be able to assist with the integration.
