I've noticed the same thing too (using a desktop.) I just got threw looking at the announcements and there was nothing stating that they were doing away with this option.
Now another thing I saw this past weekend were "shipping policies"? I don't have the option of putting in the weight and pkg. size, I'm supposed to pick from a list of "policies"? They appear to be taken from ALL my listings, but how the heck do I figure which one is for 3 oz./ 8 oz. Priority, or flat rate Priority? The first words are First class.... or Priority etc. It doesn't do me any good unless I can see the weights.
Change for the sake of change I guess
