I am trying to integrate PayPal subscriptions into a project of mine and I've hit a snag. I managed to create a product and a plan and then redirect successfully to PayPal for approval but when I hit "Agree & Subscribe" I get the following error:
We're sorry, we couldn't set up your subscription using the funding source you've selected. Please try another funding source.
and there is a "Continue" button. I tried to pay using 2 different sandbox accounts that have payment sources set up but the error remains. One of the payment sources I have set up is " The Bank Card Platinum Rewards" and as far as I know sandbox accounts come with pre-configured payment sources as was in this case.
I've, also, tried googling the error but I couldn't find exactly the same error though various other, similar, problems appear online.
I tried to go "Manage Automatic payments" and cancel all my previous subscriptions with the merchant but it didn't help.
I've looked here and here but it doesn't seem there to be a solution.
Any ideas?
