Greetings I have built a Website with Express Checkout. From a PC, it is working. I get redirected to PayPal just fine. But when I try to checkout with a mobile phone, I am getting this error from the API call (SetExpressCheckout). We could not connect you with PayPal. The error return was: Authentication/Authorization Failed. You do not have permission to make the API call. It does not appear to be my phone as i have visited several retailers who offer Express Checkout and it works for all of them. Plus I have bought items from retailers on my mobile phones without an issue. Has anyone else had this issue?
