WPML

WPML is such a monstrous thing that I don’t even want to touch, sorry. It seems nobody can use it correctly except for their authors (not sure if even they can).

I believe if WPML works with any woocommerce shipping method by default it should work with this plugin too. In other words, the plugin has no special WPML support code.

Once, I was able to translate delivery option names with WPML String Translation module. Not sure if something changed from that time.

It will be great if you or someone else find a solution and paste it here.
