I am using 'Translate My Store' app for adding a second language to my website.
I have almost set everything up, but there is an issue.
When I am on 'Spanish' theme (unpublished language) and I click the cart button, (the one on the upper right of the store, not the one that is usually above the 'Buy Now' button), it redirects me to the 'Cart' page on english.
Sincerely hope you're having a great day!

Could you share your website URL? And if your website is password protected then also provide a password?
