Connectivity and game performances depend on several factors like device processor, memory, space, operating system, connectivity, ISP, bandwith, network, etc etc etc. Too many factors to list or to discuss in detail. In my opinion, your daughter's opinion is an individual opinion, without basis. Some may say iOS devices have lesser issues because they have a better operating system. And there are numerous different Android types of devices that made it more complicated. Anyways for questions on platform parity, you can file a
forum dispute thread and discuss further with the Community Manager.
