Are you exiting the Mezzmo app or just pressing the home button to return to the main menu of the Fire TV? If you are exiting the app please try leaving it running and just use the home button on the remote to return to the menu or if you are just using the home button please try exiting the app from the menu. We have tested here and if we exit the app we can always return to it, we will try leaving it running to see if this is causing the issue.
