How can I set auto language and currency for different domains?

Topic summary

Merchant operating one domain for Sweden and the USA wants the storefront to auto-detect market and display language and currency accordingly (English + USD for US visitors; Swedish + SEK for Sweden). Currently, US visitors still see Swedish.

Actions taken:

  • Site translated via an app (process took ~7 hours).
  • Contacted Shopify support over 6 days without a solution.

Goal: Reliable automatic language and currency switching by market/domain.

Status: Unresolved. Merchant is seeking community guidance and considering changing e-commerce platform if not resolved.

Notes: No code, images, or configuration details were provided; root cause remains unclear.

As a last resort im reaching out here. For the last 6 days i have been talking to support chat on shopify with no results. My issue is this, i have 1 domain for both sweden and usa. I want the usa page to auto show in english and dollars and in sweden it should be in swedish and swedish currency. I have translated already with app it took about 7h. But still when people log on to the usa market it shows up in swedish. U guys are my last hope the im changing e-plattform.
