It looks like you are using some sort of lazy loading plugin for images maybe? I'm seeing a perfmatters-lazy class and a  data-ll-status attribute in the html for the images that isn't part of my code. I'm not sure why it would work on desktop and not mobile. You would either need to contact the creator of the other plugin or their may be a way to ignore the images in the other plugins settings.

To filter by source for the review template then there must be some reviews on the Review List page for that source.

What is the Place ID that is having issues?

There are some functions on this page...

I fixed Airbnb download last night. It should now grab the avatars. You will need to remove the reviews and re-download.

The latest version of the plugin 12.4.4 will hide the images on the front end if they are broken links. The issue is that Google has started expiring the images after a while. I plan on saving them locally in the next version of the plugin as a work around.

That would be some of the site CSS overwriting the plugin. You can right-click on the arrow and inspect. Then look for the CSS. Then you can know what CSS you can add to the custom CSS section of the review template to fix. I can check it if you post the URL.

Can you post the URL?

Once you get the agents setup you can turn on Auto Download so you don't have to keep them updated manually. Yes, it would be time consuming to do it the first time.

Alternatively there is a way to use the google place api to set up a directory style site. Look under the Tools page of the plugin.

I only see one example. did you mean to upload another?
