Those are my current settings for
Static inital page instead of posts page
Actually only 2 languages
Detect browser language: on
Use language code, as suggested with plugin wordpress seo
remove language in permalinks
Hide url for default language
media translation: on
Sync: all on
it's a working site and just now added polylang
In some top level pages links doesn't work as expected and always redirect to posts page nor the correct static page.
You can see in all top level pages redirected to same posts page
These 3 pages should show diferent information but all of them redirects to
(url to publish posts)
Need more verification but for now seems all other pages and posts work fine.
