That would make everyone nostalgic and sympathetic to the royals. It would be considered rude and improper to talk about Andrew's scandal when everyone is in shock. It would be months before it would even be "appropriate" to talk about such things.

If someone did try to bring up Andrew the response would be, "The Queen just died, you creep! Can't you let her rest in peace for a bit before you savage her family! They're going through enough right now!"

It would definitely shut up any negative news on the royals for a while.
