I am trying to integrate my Shopify store with PayPal express checkout but the moment I click on the activate button it redirects me to PayPal log in where it asks me to complete my setup on PayPal. But my PayPal is completely set up. PayPal customer service is not able to solve this issue. Anyone else with the same problem?
I found the solution, my PayPal was linked to previous store, I went to account settings and removed shopify from service providers and API access, easy fix!
