Same problem
We have a catalan home (mysite.com) and when we create the traduction mysite.com/es (2nd language) is a page that contains all the pages in one, it is as if polylang had armed its own page containing all the pages including examples of the wordpress theme we use.
I follow https://polylang.wordpress.com/documentation/setting-up-a-wordpress-multilingual-site-with-polylang/translating-posts-or-pages/ instructions accurately but the translated page has an URL mysite.com/es/home-2 and the URL of second language home is mysite.com/es. Is there a way to force URL to another one when you click on the 2nd language flag?
Any idea? Thanks!!
