We just rolled out a change to how FedEx Ground is handled as a shipping option.
Previously, "Ground" might be listed as an option for international shipping from the US to Canada even if you did not intend to provide that shipping option. We've added a new "International Ground" FedEx option and pre-checked it in the admin for all stores who are using FedEx for international shipping and were already using Ground as an option. For stores that were using Ground but not using FedEx for international shipping, the box was left unchecked.
Action for you to take:
If you intend to use Ground as an international option for FedEx but you previously have not used FedEx for international shipping, go to your store's admin shipping section and check the for international shipping option under FedEx and select international ground.
As always, please let us know if you have any questions.
