[davshop]

Hi

I opened shopify partner account and i used it to designed online store in my Shopify Partners Account; but Shopify Payments is the Default Payment Method.

I have Two(2) Stores in my Shpify Partners Account and the Two(2) Stores are showing Shopify Payments as the Default Payment Method; i have tried to change several times but i was not able to change it successfully.

My question is How Can I Change Default Payment in my Shopify Store; which is Shopify Payments to another Payment Provider e.g. to Paystack

Thanks.

Dave.
