I'm testing subscription in Sandbox using the REST API guide - https://developer.paypal.com/docs/subscriptions/integrate/ and after following every step diligently I'm greeted with We’re sorry Things don’t appear to be working at the moment when I click the Paypal buttons and sign in using the sandbox paypal account.
I see that numerous others have mentioned this error, How to test and integrate Paypal Subscription with this error?
