No connection to the Minecraft Marketplace from iOS app and no access to bought content

Hi team, 
I experience huge problems with Minecraft on iPad. I open the app, will be logged in with Xbox Live and go to Marketplace / My bought stuff. First problem: store lags a LOT, to see the content takes AGES if I do not get "I cannot connect to store, try later or check your internet connection" first - which happens recently the 99% of the time. My internet connection is perfect!
Second problem: I will see NOTHING in 'My bought sets' section, neither bought nor free of charge I downloaded - so I cannot play them. This is VERY ANNOYING!
Please help.
