Can't update stocks on listings, encounter a prompt message

Hi, can you assist us, its the first time that this msg prompt us that we need to use age verification in order to sell wine while trying to update the stock listings. It never happens before. Now it tells us to Choose Flat Rate, then select from two general shipping service with adult signature service options: "Standard Shipping with Age Verification" or "express Shipping with Age verification".

With all the upgrades eBay are doing, I would say they now require liquor sellers to use those methods of shipping.

Have you tried updating a listing selecting standard shipping with age verification ?
