No, the Church did not approve the Novus Ordo. It was approved by the Vatican II anti-church and by a man (Paul VI) who was a Freemason and an anti-pope. And I say he was an anti-pope not based on my own opinion, but on Church teachings. Anyone who joins Fɾҽҽmαsσɳɾყ is automatically excommunicated from the Church, so when I say he's an anti-pope I'm saying so according to what the Church teaches.
I agree the Church did not approve of the Novus Ordo, because you have to have a true pope that makes that approval.
Really, the Freemason thing is a moot point since a pope is above canon law, and that excommunication is not divine law. Neither would his being a Freemason invalidate the election because Pius XII legislated to suspended all excommunications for the sake of the election. What makes Paul VI a false pope is divine law - that it is impossible the Holy Ghost would have allowed a true pope to have promulgated the things he did.
Canon Law is dogmatic, any law that has an anethama attached to it is infallible, if it was once infallible it is always infallible, in order for an anethama to have been imposed it must be from the Chair(Ex Cathedra).
Dogmatic laws are Divine laws they are always and everywhere believed, if not always defined.
A Pope is not above Canon law, it has never been believed that he could be above a law with an anethama attached nor can a law that has an anethama attached be reprieved or abrogated. There are diciplanary laws that a Pope is above, but Fɾҽҽmαsσɳɾყ is not one of those. Freemasons are outside of the Church, they are heretics and enemies of the Church one cannot be inside the church and be her enemy, thus if one is a Freemason one is anathema.
Now Whether or Not Paul VI was a Freemason I do not know. But if he was he would be outside the Church.
Either way, my belief in whether or not these last 4 or 5 Popes were Popes or not has no bearing on my salvation, so long as i keep to the Infallible Magisterium of the Church I will find my way.
