Board Thread:Dragon City Gameplay Questions & Answers/@comment-11472750-20130707190058

I've had a probleming with inviting my friends to join dragon city. I send an invitation and they never seem to get it. Also out of the blue one of my friends was removed from my list. When you send presents they never seem to get the presents and the Bolts on Olympus island can not be accumulated. As anyone had these same issues and do they know a way to fix it?
