[Решено] I want to read some on synchronization between languages when using page builders

I'm looking for some documentation, that I can't find anywhere. I want to read some on synchronization between languages when using page builders. Specifically, I want to explain to the client, why is it a good idea, to use the ATE instead of creating content for each language with a page builder, and how can they set the sync back, when they are ready to move to ATE.
