I'm a pretty experienced iPad/iPhone user, but this one has me baffled. It only seems to happen on my iPad (4th gen, 64gb, all latest patches). From time to time, when I'm using an app that uses the net (web, mail, Facebook, twitter), without warning the App Store opens up and the download page for Clash of Clans comes up. This happens incessantly, almost every day. Does anyone know what's going on, and if it can be stopped? This doesn't seem to happen with any other product - that is, I'm not being barraged by ads for others software. Any suggestions?
