Hi,

I’m having an issue when using @inContext on this mutation, it always returns the cart object in English (which is the default language of the store).
Screenshot attached for reference.

Btw, the cart query works properly as it returns the correct language when using @inContext.

Any help will be really appreciated.

Thanks!
