Hi, I have used the following url to get a sandbox mastercard card to test apple pay. https://developer.apple.com/apple-pay/sandbox-testing/ I have managed to get it to work using a visa card however with mastercard I cannot. I either get 'Cannot add card' or when the card does get added it just states 'Activating' / 'Your Card is being Activated' Has anyone else had this or provide a mastercard that would actually work? I have tried every mastercard debit on that page. Thanks
