Want to view friends scores for levels

Are you connecting to Facebook or Kingdom in the game?  You won't have this feature if you don't connect to an account.

Might not be connecting properly in that case, give this a shot as it seem to reset the connection. If you have the Facebook app you should uninstall it to start with. You want to clear all cache from Safari next, I know it can be a little different depending on which iOS version it is so you'll need to search for the version you have if you don't know how. When you've done that, open Safari and login to Facebook. When you next hit connect in the game it will connect through Safari and sync your progress. Once you're done you can reinstall the Facebook app if you removed it.
