There have been many posts about issues the original PVB had with timeshare license approval in various states. Back then, California was the last state to approve the PVB timeshare license. Most states were 1-2 weeks after Florida. I think New York and possibly one more required about 4 weeks after Florida.
Also, on
DVC website for Island Tower at PVB, they show it is not approved in all jurisdictions. Delay in sales may be because they want to avoid the fiasco they had the last time with PVB. I think we started seeing DVC releasing a lot more news about Island Tower in early August so perhaps that is when they submitted amendments to all states?
I found a website that I believe shows California Timeshare licensing/amendments.

If this is the correct web site AND it's a "Sales License Change", here is what they show as current processing times.
