If the “product weight” is not set, easyRates will not be able to calculate the shipping fee.
On the upper part of the settings page for easyRates, there is a compatibility scan you can use. (If you are unable to see it, please click the 🔔 mark.)
Currently, the bell mark is not displayed, once this is closed, it will be displayed 7 days later.
Adjust the product weight and rescan to check the compatibility.
