I was using PayPal express checkout but due to some error I tried to disconnect and reconnect 4 days ago, but now its not working, seems paypal has changed settings for Indian merchants, but they should provide the solution/instructions for this, I had only PayPal setup on my store and now I'm just wasting money with paid apps, e.t.c, because I don't have any payment gateway setup on my store. i also did contact to shopify but there are also not able to provide correct info.
