Hello,
I have uploaded translations because it was missing https://prnt.sc/BhsVEzUBlmro It’s a partial translation that we got from our client. So, you can continue to translate missing strings (Loco Translate > Plugins > XStore Core, Loco translate > Themes > XStore).
To translate header texts go to Theme Options > Header builder > edit Cart element and translate text strings, Search etc.
Let me know if you finish the translation but still have any missing untranslated strings.
Regards
