The plugin can download the reviews in the original language. Then there is a translate option on the Tools page.

This is an optional setting now.

Currently, you would have to add multiple badges or sliders. One for each business. You also might want to check with Google to see if it would be a good idea to have more than one on a page.

Please update the plugin to the latest version 12.0.3. 

I just made some changes. Make sure you are using the Crawl Server = Remote and give it another try. Might take a couple of tries. 

The Review Funnel method should still be working also.

What is the TripAdvisor URL?
