Some people got the option to change it, others had to phone Tesla to get it changed.
It probably relates to how far advanced your existing order is.
Your original order date is likely a factor too, because if you switch from a RWD to a P (or vice versa) and the price for those models were cheaper on your order date, then the old price applies. And for the LR there was no "old" price.
If you ordered at a time that prices were higher than now, it wouldn't be a factor.
Just for reference, I tracked the price changes for the Model Y Performance since launch date.
The RWD prices would have changed on most of those days too, but I haven't kept track of those.
