FB connection problem

Hi friends;

i have been playing this game for 1 week; i love it so much. But not i have a problem and can not find a solution. I was playing this game in my android mobile to yesterday. I connected it to my friend FB account to check what will change :) But now i can not delete/ disconnect this link in game. I want to continue to play in my android mobile phone and disconnect its connection with Facebook. How can i do this? As i dont use FB and connected the game to a friend of mine facebook, need to delete this link and continue to play in my mobile.

Thank you su much.

you could try delete the data and cache, and if that doesn't work, completely uninstall app and reinstall. also, you could try contacting Nordeus Support
