Thanks for getting back.
I have a shared domain with 2 markets (Belgium and The Netherlands). For each, Dutch is default language and English is available via /en.
l’m physically accessing from Belgium, using incognito mode and my browser is confirmed to be set to English, yet I’m not able to get auto-redirected to /en no matter what I try, despite the option being enabled.
Manually selecting English from the language selector dropdown menu is working.
I think all conditions are met, but ‘having translating added’ is a bit of a vague one to me…
