Product tabs is a feature we are working on adding to our themes. We have added it to Symmetry, Boost, Showcase. Currently, we only have the ability to show the same pages on all products. For now, you can try using this free app that gives you the ability with creating product-specific tabs.
Please note it is the responsibility of the app developers to ensure their products work with all themes on the Shopify theme store and if you wish to make changes or requests that involve changing them, you’ll need to reach out to the relevant developer if you do have any issues during installation.
