If it was, surely it ceased to be advisory when parliament triggered Article 50
Parliament didn't trigger A50, the government did. There is a difference between parliament and the government.
Parliament voted to give May permission to trigger A50; the Miller court case which required this was to prevent the May using Henry VIII powers which would have bypassed the approval of parliament.

The referendum *never ceased to be advisory*; that was its legal status and its legal status has never been altered.
It's such a shame that no-one on the Leavers' side seems to explain these facts to them. It would really help their understanding of how parliament and the legal system works.
