Here the solution i find instead of whining here non stop for those who can't verify app. Delete the app and reinstalled again from the link given, it can be slowed but wait patiently for it, best is overnight. Next step once it's downloaded, go to your General, Device Management, trust the new one will do. Then go to start up your walking dead our world app, if u saw "Reload", just reset the game & it will load properly, go through the short 2-3mins tutorial, once tutorial over, click on top left corner profile, select connect to game center and choose back your previous profile name that u connected with & you done.
