The debacle in Australia, albeit a hot mess, was definitely not the norm. We booked a suite gty for our recent sailing on Anthem. I would randomly check the availability of cabins (not looking to change, just being curious), one day it would be sold out, two days later there would be balconies only available, a week later everything was sold out except suites. Not sure when your cruise is, but keep checking the availability, if something opens up see if you can switch cabins.
As firely stated, can't worry about what you can't control.
