Very confusing indeed! I don't like when there is different information within a company. They should have some document shared with all SAs in their data system.
I live in Sweden (Europe) and it seems like several countries in Europe has information about it being discontinued. My SA normally has no information about things that are going to be discontinued and she didn't even know I was interested in this pochette (so at least not a cheap trick from her). And personally I would put more trust to information from Europe than USA since LV is based in Europe.
But of course, I wouldn't recommend anyone to buy the PA just because it is going to be discontinued. I had planned this purchase for a year, was supposed to buy it in September and buy a summer bag in May. So instead I got a fall/winter bag in April haha. Hopefully I will be able to buy my summer bag in June
