When we replay session, Tealeaf will get data from webserver with using its own user agent string of Tealeaf server.
For this reason, if website have the data in different server for each desktop and mobile site and distribute access automatically by some system,
we cannot replay session captured from mobile because Tealeaf isn't able to get the data for mobile site.

We think you have to enable to get the data to web server using user agent string captured in session replay in order to fix this problem.
I hope you fix this issue for all of users using the website system like this.
