hello, you can add two pickup addresses in your ps seller central. I also did the same and both addresses got approved. The only problem i am facing is that the lsp is coming only to my primary pickup address for shipment pickup. For the second pick up address, i need to go to lsp's counter to handover the shipment.
I am trying to sort out the problem, please help if u find something on this.
BTW, my ps got approved just a couple of days back, still learning...
