Perplexity app for iOS: Bad response for European Train Route Query

 iOS 16.3.1

Perplexity - Ask Anything app for iOS (version 1.3.0)

Date: 04/27/2023

Description:

I don't think the response that Perplexity gives to these two questions is accurate or appropriate.

Here's the query:

What's the longest train route in the European Union? 

Here's the response:

The response.

Here's the problem with this response: The train route they mention runs from Adler to Vorkuta, Russia. 

Russia, of course, is not a member of the European Union, and the train line appears to run entirely in Russia.  

The response to "What is the longest train route in the European Union" should NOT be this line. 

Steps to Reproduce:

1. Open the Perplexity app for iOS

2. Ask: "What is the longest train route in the European Union"

Result: Perplexity's response to, "What is the longest train route in the European Union" is a train route in Russia. 

Expected: Perplexity's response to "What is the longest train route in the European Union" query should be train route that begins and ends within the boundaries of the European Union
