Update: We are doing a maintenance now to fix this issue: http://supr.cl/V4oryu
Seems like some players are not able to load the game, and get kicked out during the loading. We are investigating this as a top priority, so stay tuned while the team is looking into this. I'll keep you posted as soon as we have news!
If you have experienced this behaviour since a couple of hours ago, please post in this thread which device you use and which country you are playing from. Thanks!
Sorry for the inconvenience!
