I'm trying to sync my account with Facebook to obtain the free gems. When I attempt to do so, a message appears saying "Dragon Era would like to access your public profile and friend list." I press okay, but then the screen goes back to the Dragon Era Social Menu, and does not give me any gems. In addition, the Facebook option is still showing, meaning it hasn't synced yet.
I've already tried to fix this by force-stopping Dragon Era, clearing the cache in the Facebook app, and restarting my phone.
If it helps with troubleshooting, I am running the game on a Galaxy S5 with Android version 4.4
