This is the most problematic bug I've found thus far; otherwise, the game mechanics work semi-well.
I can minimize and expand the brown/red-ish bars shown as 'Country Selection' and 'Canada: Quebec' below
However, as shown below, the button(s) that I need to click - such as acquiring Canada: Quebec - often disappears due to the screen size
If I attempt to drag the brown/red-ish bar (on the screen) by directly putting my finger over it and sliding it up or down, it simply shakes the browser and nothing happens in-game.
If I do the same but slide the bar left or right, the below happens. That is, thanks to Safari's installed features, I either go back to a previous webpage (sliding left) or the following webpage (sliding right).
And I don't think it's a problem with Safari or screen size alone, it's some weird combination of displayment issue I believe, because I am seemingly able to drag the bar on neither my iPhone nor iPad.
