Synchronizing and translating meta
Gato AI Translations for Polylang can synchronize and translate meta data from your theme and plugins.
How it works
In the Settings > Meta Configuration
tab, define the meta keys to copy and translate.
For custom posts and media, use the following inputs:
Copy Meta for Custom Posts and Media
Translate Meta for Custom Posts and Media
...and for tags and categories, use the following inputs:
Copy Meta for Tags and Categories
Translate Meta for Tags and Categories
You can indicate if the provided entries are included, or excluded.

Each meta key can be defined via its name, or using a regex:
For instance, any of these entries match meta key "_yoast_wpseo_title"
:
_yoast_wpseo_title
/"_yoast_wpseo_.*/
#"_yoast_wpseo_([a-zA-Z]*)#
