I print my labels through eBay and use bulk shipping. This morning none of my international sales had the tracking numbers automatically added. These sales then showed as "sold " but not shipped. The payment went through fine and I was able to print the international labels/ custom forms. When I tried to add the tracking manually, eBay's system would not allow this. So, a call to customer service revealed there is a "bug" in their system. The rep wasn't sure if it only affected international labels/ sales. She was able to add the tracking for me so that was great. Hopefully,I won't have to call again as approx. 30 % of my daily sales are international. (Also , no I don't use the GSP). I'm still recovering from the label debacle of 8/ 15 - 8 /18. So if anyone is experiencing this you are not alone!
