They can still move you around, due to "operational and security reasons".
In Dec about 2.75 years ago, (I think it was Dec 2019), I had booked AKL - BNE on their A330, always had window seat request in my QFF profile.
And they have 99% of the time gave me this, on their other flights that I have taken with them.
But, just because I was a bit late doing OLCI from AKL, they popped me into the middle of the J cabin, ie, no window.
To prove who you are when you log into your account from overseas, they can be a bit late in sending the 6 digit 2fa code to your mobile phone number, for you to log into your QFF account.
If you are lucky, that 6 digit code comes straight to your mobile, if not, your wanted seat could be snapped by others.
