I have been trying it for an hour but I’m not sure what’s wrong. I have created test accounts for both merchant and buyer via developer.paypal.com. Replaced woocommerce seller details with sandbox’s. During checkout, it redirected me to sandbox page with the test merchant details which I think there’s nothing wrong.
But, whenever I try to login with test buyer paypal account, it keeps saying “Please check your email address and password and try again”, I’m pretty sure I enter the credentials correctly, I created another buyer account but it still saying the same thing. What did I do wrong?
