Ender chests disappearing

Hey guys.

So I play on MCPE on my iPad, so I don't know if I'm using Java or Bedrock, but anyways, Something weird happened. So me and my friends have this little Minecraft survival world. My friend and I were building a bridge in the nether over to a portal. I placed down an ender chest to give my friend a bow, but then I realized the bow was in my inventory. I took the bow out of my inventory, and threw it at my friend, then, I got kicked out of the Minecraft app. When I was giving my friend the bow, I didn't mine the ender chest. When I relogged, the ender chest was gone! I had one on the bridge, and one in my inventory, and they both were gone. I don't know what happened, but I would love this fixed.

Thanks! 

P.S. I the version on my iPad for Minecraft is 1.14.60
