In eBay sandbox environment marking item as shipped or payment received do not work. After pressing mark appears spinning icon and after few minutes redirects me to eBay sign in page. I sign in and no item is marked as shipped or that payment is received.
seems like the bug still exists, along with a ton more in the sandbox. I am unable to create a test paypal account as well. i am dead in the water on a fulfillment project because of this. Please tell me there is a work around other than testing in production
