Hi @bl0h@w4dd325 the latest version of the Postman (v10) has a redesigned API builder experience. Read my blogpost to know more.
As for validation from schema to collection, we are reintroducing that flow in Postman v10 with the improved feature set. For now it is not available in the Postman V10. Iāll update the thread once we have the feature back again.
