Two languages configured: en and de.
When I visit website.com it forwards me to the correct language slug, depending on my browser language:
website.com/de or website.com/en (default language)
However if I visit a subpage url with the same slug for both languages (for example a perosnal name that doesn’t get translated) without a language slug it always forwards me to the default language version of the subpage:
With my browser language set to German, visiting website.com/famous-actor forwards me to website.com/en/famous-actor. Intended forward: website.com/de/famous-actor.
