Liam here from Shopify - thank you for your question :)
Great to see you are looking to add product tabs to your product pages on Debut. I have tried this customisation on Debut too but I was not able to get it working either. The best alternative would be to use this app: Easy Tabs. I have tested this on my own store and I can confirm it works with Debut:
Hope this helps Elizabeth, if you have any other questions, just let me know!
There is no reason for this not to work. In Debut sections/product-template.liquid is the section that handles the logic for the product page.
Try to implement the tabs in product-template.liquid.
Thank you Liam! I will check out this app.
Mircea I did originally attempt to install tabs in product-template.liquid but it didn't work. I used this tutorial: https://help.shopify.com/themes/customization/products/add-tabs-to-product-descriptions
