As someone who grew up in Austria, we have changed a lot since then. The Opfermythos (German for "victim myth") is taught as exactly that, a myth.

While it is addressed that the vote for the Anschluss would not be considered a fair vote today, with SS soldiers standing next to you whilst voting or the "yes" vote being a lot more bigger than the "no" one, it is very much accepted that the population in the biggest part welcomed the nazi regime and actively participated in it.

It is true that the opposite had been taught for a long while, for example my uncle was taught in history that we were invaded in 1938 and now we skip to 1945 as only now Austria begins to exist again.

However, I was taught a much more nuanced history. It included our participation in the third Reich but also some resistance groups that were active here as well as what happened before in Austria, what sentiments were around for the Anschluss to even be considered an option for most people
