Aura store publishing language and checkout failures
Key Takeaway
For a B2B store built on an Aura template, Salesforce recommends publishing the store in English to avoid checkout failures. Buyers whose language the store supports still see the store in their own language, because translation follows the store's supported languages, not the language you publish in.
Some B2B stores still run on the older Aura template instead of the Lightning Web Runtime (LWR) platform. For these Aura stores, Salesforce recommends publishing the store in English to avoid checkout failures. Publishing in English doesn't lock buyers into English. After the store is published, it's still translated based on its supported languages, so buyers who use another supported language still see the store in their language.
Aura stores and LWR stores
Starting with Summer '23, all new B2B stores are built on the Lightning Web Runtime (LWR) platform. Some older B2B stores still use the Aura platform and run on an Aura template. Parts of the Commerce app UI still refer to Aura features and components.

If your store is a B2B store built on an older Aura template...
