We have used a custom theme which is not available in shopify theme store, We have used Help Center Faq app to display in front end, But the App css and functionality is not working and not even displaying the template selected in Help Center Faq app. Its displaying the custom theme functionality and css as Default Is there any way to override the custom theme css and functionality and to use the app css and functionality
The app should have a supported template list, contact the app support team. Additionally, it seems your theme css it's overriding the app files. That's the reason why you shouldn't use unsupported themes unless you know what you are doing. Nevertheless, you can disable the theme css by creating a new layout file without the main css file in the header and only using the app css specific for that page.
