I am rewriting paragraphs on the home page. It had been previously translated into Traditional Chinese, Simplified Chinese, Thai, and Vietnamese. I want to better understand what will happen when I make changes to the home page in English. Will it be automatically translated and updated or do I have to resubmit it by reviewers? How about if I have a translation pending review .... if I make changes to the home English home page and automatic translation is on, will the page content of my pages submitted for translation review automatically update? Will language reviewers now have two requests for reviews or does the initial request get overwritten? Or do I need to delete on of the requests?
Before assigning your ticket to one of my colleagues, here relevant links to our guides which will help you get answers to your questions.
The answers to your questions depend on the settings you have on your site. Those things mainly depend on the settings in WPML -> Settings -> Translation Mode and Automatic Translation. Please find the answers at the following links.
