I am Jayanta Kr Mallick from India. I have recently created a Shopify store (https://www.womenfashionatoz.com) and selected my PayPal business account (PayPal Express Checkout) as payment provider.
But I have been facing a problem regarding Payment. Whenever I go to activate PayPal Express Checkout through Shopify settings, PayPal is asking for Third Party Permission Username and cannot go ahead.
In this situation, I am requesting a solution so that my store runs smoothly.
