I have installed the Expedia app several times, changed passwords several times, uninstalled and reinstalled the app, restarted my phone after chatting with an agent, and still it will not let me sign in. This app does not work. I have never had any issues with any other apps. The agent I chatted with is going to send this to the coders involved. But I don't hold out much hope!!!! It would have been nice to be able to use the Expedia app on my upcoming road trip, just for convenience sake!!!
