Log in redirect sometimes does not work and fails to log-in / authenticate

[benlane2003]

Describe the bug When logging into Spotify and staying loggin in via "Remember me", if I attempt to re-authenticate the Spotify mobile service, after restarting the program, the log in window pops up but it is a blank page and when I go back into my program manually, it does not authenticate and throws a "Unable to get any application redirect arguments when expecting them" console message.

To Reproduce: If you can, list some of the steps you are taking

• When log in window pops up to log in to Spotify, check the "Remember me" box and log in. It should work just fine. After that, either end Spotify4Unity's mobile service or restart the app/program and attempt to log in.

Expected behavior After website pops up it should redirect back to the program and authenticate the log in.

Platform:

• Android

Unity Version:

• 2019.3.0f.6

Found the problem, for anybody else that is having similar issues on Android: How I fixed mine is adding "&show_dialog=true" to the end of my log-in url. It seems like the "show_dialog" parameter is always set to false, thus, hiding the content of the webpage (the web page is a page asking the user if they want to grant the APP permission to use said user's Spotify account and info). After adding in this parameter and setting it to true, the page will no longer be blank and the user can hit "accept" to redirect back into the APP and receive the callback.
