Unfortunately, Linguise can not translate dynamic content that is loaded asynchronously. It has to see the actual HTML content when the page is loaded.
It’s possible to handle it, but it requires a custom development for each plugin/extension that uses the AJAX request.
We’ve done some integrations already, like WooCommerce and emails translations, but unfortunately, we can’t do integrations with all existing extensions for all CMSs. If you’re in this case, please reach out to our support team or the forum to ask for a custom integration. We’ll check the feasibility and the number of requests we have to validate the release.
