The “+” symbol on the app is the equivalent of the “More/Less” button on the web version. As I mentioned in your original forum topic, I set this particular course that way intentionally, so that the student has the option of learning only from the picture without the English translation. Have you tried the suggestion I made in the edit I added to my post in that earlier topic (clicking on “Always show” in the “Edit column” area of your course, via the blue pencil icon to right of your column header)?
In this other course https://www.memrise.com/course/20690/a-world-geography-with-audio/, I have it set so that the student sees the picture and the English, as well as the ‘attributes’.
I’ll send you a PM on this forum explaining the settings I have used for these two courses, which may help.
