Got it! Not sure what I did differently but it works now. Thanks!

I tried deleting the plugin and doing a clean install but it didn’t solve the issue.
The error message went away but it still wasn’t able to find any reviews at that URL. “Unable to find any new reviews.” It was able to pull them for a single room URL and from the sample user URL. Pretty strange.
I’m getting the same error on my site with the url: https://www.airbnb.com/users/show/3501259
