Not loading on wifi - no multiplayer

If you're on a world and turn the wifi on then you can continue to play that world without a problem, but on the options pages - choosing a world / signing in then the game freezes and none of the buttons are clickable. If wifi is on while loading minecraft then there is only a white screen after the mojang screen.
Playing over 3G/4g or without any connection there is no problem, but obviously we're unable to join each other's worlds. We all are experiencing the same thing. We're playing in a iPhone 6, an iPhone 5s and an iPod 4, and we're all updated to the latest 1.1.2 since 27th June.

It was doing it before this latest update too. We hoped this update would fix it. I think it's been since the last major update at the beginning of June.

Hmm, then, the issue is probably happening while the game is trying to find peers in the same network to form a LAN multiplayer game. Something must have regressed in 1.1.x updates.

I'm seeing the same issue, though from a more specific cause. I've got a local WiFi LAN that has no Internet access that I use to let kids play together while guaranteeing their parents that they can't surf the Internet instead of playing. Lately (sorry, can't pin down which most recent version broke it), if the kids fire up MCPE with WiFi on and connected to my neutered LAN, they get the white screen described. Turning off WiFi on their device causes a Global Resource Crash, but they are then able launch and play their own games. Turning WiFi back on causes their game to freeze. [Side note: this seems to be a new behavior for MCPE, as I've always previously found that the only way to get a game to recognize a change in WiFi access was to quit and restart the game.] However, if I shift all the players to a WiFi network with Internet access, they have no issues, as before. So, as PHO surmises, I suspect there's something going on when the game is trying to find peers to form a multiplayer game that gets hung up if it can't get a response to queries trying to find WAN peers/resources. Those two things (LAN peers and WAN options/resources) need to be separated, with some robust error handling, especially if games are now able to sense changes in WiFi access mid stream.

Bump. Having this same issue on Ipad Pro 10.3.3 for PE. Noticed once the white screen went away, I could see a Global Resources Error and the screen was frozen. Backed up worlds, deleted app, reinstalled and turned off wifi and it works fine. Turn on wifi, and it whitescreens and crashes. There are no resource packs installed just the one the game comes with.
