I have a i18n folder with 7 csv files which contain keys and translation into 7 different languages.
Then I go into admin panel and in General->Locale options, I select a language which is contained in my i18n folder.
All works fine as expected (I see correct translation in frontend checkout page).
But when within admin panel, I select the locale which I don’t have in my i18n folder, then in frontend checkout page I only see translation keys (and not translation them selves).
Is there a way to set a default fallback language to English for example, when the current selected language is not supported?
