The control <vtex:contentPlaceHolder id="Acessorios"/> should bring a view of related products set as the type acessorios to the product page. However, currently, this control is not displaying this view, so the related products set will not be displayed.

• Use the control in a template. (To help with that you could create the vtex:contentPlaceHolder following documentation: List of controls for templates)
• Check if there is any product with related products set as acessorios. The CrossSeling API could be used to check this info for a specific product - Get Product Search of Accessories.
• Furthermore, on Portal, load the landing page that uses the layout with this control.
• See that the related products will not be displayed.

Use other CrossSellings controls or customization with the API Response.
