Translation missing error

[rbtu]

We have a problem with the translations in our Shopify store. Our theme was originally set to English, but was changed to German as the default language in the Shopify settings under “Language”. We have also installed the “Translate & Adapt” app.

The translation file is correctly located in the Shopify code under locales/en.json and contains all the necessary translations. Nevertheless, the error message “Translation missing: de. ...” is displayed in many elements of our store. An example of this is “Translation missing: de.templates.search.title”, although the corresponding key templates.search.title is present and correctly formatted in the de.json.

We suspect that the problem may be related to the use of multiple markets that could use different German language versions (e.g. German (Deutschland) and German (International)). We have already seen this several times.
