Hey there ! When I launch the game, the title screen appeared, and the connection to Playfab start. However it always stopped and said : Unable to Sign In. There is a problem with Steam. Please restart steam and try again or send a email to the support. I don't know what to do ! Thanks for help ! PS : There are some screenshots of the error just behind this post !
I assume you have restated steam. Maybe try a PC reboot. Otherwise email support@uberent.com to look at your account.
Thanks for helping, I've already try to restart my PC but nothing change. I'm gonna send a message to the support !
