How do you finish learning a Deck?

[MS]

I have problems navigating back from a deck (learning mode) to the overview of all decks (start screen)
Currently the only solution I find is is to Terminate the application in the doc and relaunch it.
THis cannot be the right way.

Sometimes the back arrow at the top right is hidden, but you should always be able to tap up there to return to the main Decks screen, even if you don't see a button for it.

When you started the app, you saw a title bar at the top of the study screen, which had the back arrow. You can tap near the top of the screen to toggle the showing of this on/off. So just tap at the top to turn the title bar back on. If you changed to one of the new card color themes, the study screen is always "full screen", but the back arrow at the top left will always work and the setting icon at the top right will also work.
