Downloaded the latest Minecraft PE on tablet and experiencing problems with old and new worlds; portions of buildings in old worlds not showing up or non-existent, and in new worlds the additions made previously do not save. Neither is associated with any crashes, just normal start up and leaving the game. Need resolution - several people have commented on the comments section for Minecraft PE on Google Play store, so it appears it is happening across multiple devices and android versions. Screen shot showing flooding, have of the buildings gone that were full buildings, etc.
