I'm using the latest version of your SDK. I have an issue with the editor extension that despite the fact that my title is selected, whenever I open up editor, I should open settings window and click save in order for title data to be saved and I can call playfab APIs , otherwise instead of titleID.playfabapio.io , i'll have an empty subdomain.
The new issue is that when I choose HttpWebRequest, it will return back to unity WWW and I have to redo it time to time when I open the editor.
Two questions
1- Is it a known bug,
2- Where does playfab save these values
Another thing is, the new extension or maybe the servers don't work with www anymore and many of the calls return 500 server internal so I guess you should remove the option of using Unity WWW or fix the issue (former should be ok since HttpWebRequest is not experimental anymore)
