You claim that the Avengers Tower being sold is proof that WtG is non-canon? I just came out of the movie and there was a several month gap between the events of CA:CW and SM:HC in which the WtG events could have taken place?
The NBA Finals occurred in 2017, while SM:HC is in 2016. Therefore WTG can't be canon, beacuse we can see in that video that the Avengers Tower is still used by Stark, and we konw for a fact he sold it in SM:HC, i.e 2016. Just like the "Team Thor" series, it's no canon.
