I’m aware of similar questions/issues in this forum like Woocommerce Account Builder: Dashboard Template overwrites custom endpoints or Woocommerce my account : custom endpoint or Custom WooCommerce My Account endpoint
but none of these threads resulted in a clear, up-to-date response to this question. I’d be quite surprised if bricks doesn’t support any way of custom account pages, as this seems like a common requirement for plugins & advanced Websites to me.
