Allowing return shipping fees on Plus shops

How do I enable the ability to add return fees on a shopify plus store? I see that stores on other plans are able to add a fee in the return creation UI of the admin. However, the plus stores I have access to as a partner are unable to add a fee for a return. This is despite enabling or disabling return rules in the store policies and creating a new order to reflect those new policies. Any help here would be hugely appreciated. Thanks!

Plus store (no fee available in summary section):

Other plans (fee can be set in summary)

Thanks!!

We’ve figured this one out. There is an “Exchanges” feature in Plus test-drive that needs to be enabled in order to allow return shipping and restocking fees on returns. Note that this feature will “auto-release” on Aug. 19, 2025. See here for details on test drive: https://help.shopify.com/en/manual/organization-settings/test-drive
