My account information has been changed but I didn't do anything (Coins, Friends list, Thumbs-up, etc)

Please check and see if you have logged in with the right account.

If you have logged in with the right account and there are still stuff missing, it might be because of bad network connection.

Please check your network connection.

If it still does not work, please go to the Menu(≡) located at the top left corner of the screen, click on "Settings", and click "Go to Help Center" and submit a request.
