The way they are handling this is a bit wonky. You would think the opportunity to notify you would be in the statement itself, but that message implies a separate notification is coming.
As far as I know, nobody has received an official notification, yet if anyone tries to add an AU now, it shows as $195 online.
Contacted online chat. They said that notification was sent out to folks who have AUs. I did not get notification because I do not have any AUs on my account. Can folks who have AUs prior to Aug 17 share data points - did you get notification about the AU pricing change?
