Hi. i have installed the go sweet spot ap and integration is saying sync but its not coming through when i test the shipping. Do i need to do something under settings , shipping and delivery as the only carriers i can choose is UPS or fedex. Im on shopify basic plan but have changed to anual billing to get the integration. Any ideas or help please. Sorry just really frustrated with shopify support pages.
I hope you are looking for integrating your own carrier account and display calculated shipping rates from these carriers. With the annual subscription, you will get the carrier calculated shipping feature for free. Since you have already switched to annual plan, you only need to contact Shopify support to enable the feature in your store.
