I'm having this same issue. I played PE on my old tablet for a few years until I got a phone, which I then transferred those worlds to my new phone and deleted Minecraft on my old tablet. Well this was a mistake, since when I tried to open one of the old worlds from my tablet, they had this same issue. All of the worlds but one had missing chunks, and only one of the worlds that had missing chunks actually had a trace of any of the builds I had done. All the rest's missing chunks were any of the chunks I had interacted with (breaking or placing blocks/items). If there is a way to recover this without the original device, that would be great.
Update: I tried doing the same thing with another device and this time the missing chunks were all the chunks bordering the chunks I had previously loaded, so this time I kept my builds, but there's a massive chasm with void at the bottom surrounding the entire thing.
