Many have noticed the recently released update for BBC News Mobile has been withdrawn with updated installations being reverted back to 3.8. We've contacted the developer, Lawrence Gripper who has revealed to us that a serious bug was present in version 4 that caused the app to fail to when booting up.
Because the update has been withdrawn from the Windows Phone Store, those who have updated will be alerted to another update being available - this is version 3.8. If you're not experiencing issues with the recently rolled out version then you may wish to ignore the notification, but should you be affected it's worth rolling back.
The good news is the bug has been addressed and another update is currently being certified, which should be with us shortly. You can download BBC News Mobile from the Windows Phone Store for free.
