How to translate promotions?

This was supposed to be fixed as part of #3187803: Promotions always appear in original language even they are translatable. → .

I am trying to update to last version of Commerce. We are at 8.x-2.36, but that fix is old, code should be already there.
I can't figure out why the translation is not showing properly.

Yes, I saw that issue that's what I am a bit confused.
I have noticed that using the Language switcher doesn't work, but if I empty the cart and put a new product in another language it shows the proper translation, but if I change the language again, everything changes except for that Promotion label, which is a discount on shipping.
Has to be some cache issue

yeah, the adjustment is added on order refresh (which happens on order save), so a change has to be made to the order for the right language to be reflected. If you switch back & forth, you're going to experience issues. The translation happens from the order processor which then adds the adjustment to the order (and it's saved using the current language)

Yes, it seems it's related to this https://www.drupal.org/project/commerce/issues/2981193 → which makes sense since the order is "frozen".
Some labels like Subtotal were changing, but then again those are not adjustments.
Thanks!
