I have lost access to my content purchased in the marketpace. I am also unable to view the marketplace itself. I am still able to view my minecoin balance, but content won't load and I get a message telling me that I need to check my internet connection. I know the issue is not my internet connection because it still allowed me to purchase more minecoins. I added my Xbox account to a different Xbox. When I opened minecraft on that Xbox I ran in to the same issue so I know the problem isn't on a device level. I also tested my internet by connecting the console to my phone's WiFi hotspot. The issue persisted so I know it is not my home WiFi settings either.
