Update: It’s a bug in the new update with the bees. I was having this issue on my iPhone after it had just updated, but then I went onto my xBox and all my purchases from the marketplace were there. (Because i hadn’t updated the minecraft on my xbox) You all should be getting your purchases back soon.
They should be back in the next update. I was having the same issue on my iPhone, and then went onto my xBox signed into my same account, and all my purchases were there. I’m assuming they’re there because I haven’t updated it yet.
Update: Minecraft Pocket Edition updated today. Still am missing Marketplace content. And I keep getting logged out of my Microsoft Account.
