At some point we will be enabling translations on all entities in Drupal 8. However, we are not ready yet so in the meantime we would like to set all of the entities (content types, taxonomy terms, paragraphs, menus, blocks) to be defaulted to English language. We want to do this because we do not want any entity to have a language code of undefined (or und).
I am unable to find the setting that will allow us to default all entities to just English.
How can we set the default for all entities as English?
