When you apply the ‘Fan Pass Gated Product’ app block, this will hide the variant picker, quantity selector and buy button so the purpose of the gated product page should be to entice your customers with what they can unlock and incentivise them to own your Fan Pass.
You can do this via the product description, the product visuals, the product name or take your gated product page further by adding extra blocks to your template to take your product page to the next level.
