Polylang and posts : main language by default ?

Hello,

This is not a native feature of Polylang. However there are 2 ways to achieve this:

1. The synchronized posts with Polylang Pro: https://polylang.pro/doc/synchronized-posts/
2. Another solution proposed by a Polylang user: https://jeanbaptisteaudras.com/en/2019/10/running-a-bilingual-blog-with-polylang-display-posts-in-the-available-language/
   

The solution 1 has been preferred to solution 2 in Polylang Pro mainly for performance reasons.
