We are facing this same issue and no help from customer support or technical support rather. With Sandbox api all working fine except Mastercard payments. With Live API details when user tries to make payment in android mobile application, we get MERCHANT DOES NOT ACCEPT THIS TYPE OF PAYMENT. SAME ACCOUNT account card payment in website but not in mobile application. There is not support received on call. Atleast i hope we get support here asap in an hour. We have integrated paypal with Live api details for android mobile application but it does not take payment with LIVE API and client ID but it takes payment in SANDBOX mode. Mobile Application description : We are building hybrid e-commerce mobile application to work on Android and iOS platform using IONIC framework. I have attached a screenshot of the error we get. Please note : In sandbox account Visa and Paypal account payments worked but Mastercard payments failed. In Live api apk of android application, none of the payments work because of which we cannot go live. If this is not resolved asap then we will need to switch from Paypal as this has been going on from a week now and i still do not have any support.
