When I open minecraft I can't seem to access any online options. The marketplace will bot load, realms can ot be connected to and achievements will not load. I am clearly signed in as my gamertag and avatar are loaded properly. This problem is resolved when I uninstall the app and reinstall it from Google playstore. Once the app is newly installed, I can log in ans access realms. Once I close the app and reopen it, the problem of not being able to access realms occurs again until I uninstall and reinstall again. I only get one chance to play on realms each time I install the app.
