I had this problem as well and this is what fixed it. 1): Logon to your Facebook account .. 2): Go to the Candy Crush Saga Game on Facebook (where you would go to play it on Facebook) .. 3): Open the App on your computer or tablet, etc .. You should now be able to Login and Sync your progress with Facebook.
Apparently something changed in the game software. What I did to fix the problem was to access the Candy Crush Saga game on Facebook, then I was able to resync the App on the Windows 10 Laptop with the Facebook progress. Not sure who changed what, but it had to have something to do with the version on Facebook. For now all…
Same problem here. Unable to connect to Facebook. Candy Crush says "connecting to facebook cancelled" ... It was working about 4 days ago ... Windows 10 Home 64 build 1709 ... Please fix this
