Please this is really importent and I do not know why this is not yet implemented

yeah this needs to be done asap. I’m selling in the german market and feel like it’s hampering trust a lust during checkout.

I’m from Mexico, and it will be really useful to have Spanish language support on checkout.

Absolutely critical for me. Not having a checkout in my native language is a deal breaker for many, unfortunately.
