I have spent a ton of money on candy crush and candy soda crush. The past few months I cannot login to Facebook on my games. I have tried from the game and from Facebook. I am very frustrated.
You just have to clear Safari and then log in to the game again.
On your phone menu, go to SETTINGS > SAFARI > CLEAR HISTORY AND WEBSITE DATAOpen Candy Crush Soda Saga, click connect and it will take you to the browser, enter your Facebook info and that's it.
