When I want to join a guild, fight a dragon or enter the shop, I get an error message saying it cannot connect to the shop. My game was downloaded from the play store and even reinstalling it or playing on other devices did not help. Are the servers down in Europe? The problem stated about 16 hours ago.
Edit: It works when I am not connected to my home Wifi so I need to hide my connection. A bit annoying but it works.
