Hopefully I'm in the right spot. On Feb 11th we moved our domain from Yahoo to Shopify. After this, our email quit working. Yahoo says they have ran every diagnostic and there should be no issues. The last response I received from Shopify was it takes 24-48 hours for domain changes. It has now been 4 days since our domain has been changed. Does anyone have prior experience with Shopify hosting your domain and Yahoo providing email support?
