There is currently a bug for the Minecraft Bedrock Edition for the Xbox One. When you game-share content from a friends account, the majority of the content will now work. For example let's say they have 20 DLC's, only 3 will work for you.

On the Minecraft Windows edition (Better Together Cross-Play version). At one point I was able to play all of my friends downloaded content like the Simpsons skin pack, the Moana skin pack, etc...now only a few work like the Fallout Mash up, Campfire Tales skin pack and Greek mythology. I have tried multiple troubleshooting methods such as uninstalling and reinstalling the game. Hard resetting my Xbox, getting on his account and trying to redownload everything, and more. Still nothing has worked, this must be an issue with the game since many people are experiencing this. I haven't been able to use most of the content for months now. Can this please be fixed? This is something many are going through so hopefully reporting this issue can help.
