For the past couple of weeks no-one in our household has been able to access minecraft pe while our wifi is switched on, meaning we cannot play multiplayer together. With wifi switched on all we get is a white screen after the mojang loading screen. With wifi off it loads easily and all options are available and we can play all our worlds. If we turn on wifi during play it works if we're already on a world, but freezes if we're still on the options page. We've all bought this so we can play together, which we did easily up to a couple of weeks ago, so this is really frustrating
