I updated Minecraft Bedrock on my iPad to 1.17 when it was released. After updating, I was able to play on my worlds, and everything seemed normal. This morning (Wednesday, June 16) however, I went to play Minecraft and all of my data was missing. I had lost all my worlds, resource packs, behavior packs, and saved servers. The only thing that I still had was my skins that I made on character creator (my imported skins weren't there).
