Synchronization of the cart across domains

Hello.

I using Polylang pro for wordpress and woocommerce with multiple domain names. I noticed that synchronisation of the cart across domains didn’t work.

It is very inconvenient from the clients side. I would shut down a store like this, where the shopping cart disappears when you switch languages.

You claim here https://polylang.pro/downloads/polylang-for-woocommerce/ that synchronization between domains will work

How can synchronize cart between different domains?

Waiting for your reply. Thanks
