We have a block theme and a child theme. The block editor also allows to create themes to be saved on database, not physically on the disk (on theme folder). And the theme we use seems to be created without thinking about multilingual websites.
So we are setting home and blog pages to static pages on settings > reading page. And for language specific main blog pages, we already have block templates saved to database and assigned to this blog pages, but WordPress overwrites it with parent theme's designs.
How can we force WordPress to load a specific block template on specific languages for specific pages(blog home)? We use polylang for multilingual.
