Everything to do with the Minecraft store refuses to work. Any time I try to download a texture pack load my skins, download a world, it doesn't work. It'll download the packs, but then it'll sit on "Importing content" and not do anything. Also, whenever I load into Minecraft, half the time my skins refuse to load, and grays out the store saying "Invalid Session" and I end up having to close and reopen Minecraft a million times before it finally opens up. By then I've lost interest in Minecraft, and move on to a different game.

To duplicate either one of these scenarios;

Open MC bedrock on Xbox

The first issue usually begins after opening

Once you're able to open Minecraft, 

Download a world, texture pack, or anything from the store

Sit there for hours on the "Importing content" screen
