The upper right X to close the purchase pop up is FAR TOO CLOSE to the newsfeed icon. Roughly 50% of the time I mistakingly tap the newsfeed.. then have to wait for it to load.. then realize that after you close the newsfeed that little Close X NO LONGER FUNCTIONS. So I have to force quit/relaunch the app and then CAREFULLY ensure I don't mistakenly hit the newsfeed icon again...
All this could so easily be solved by...
A) Move the close X to the left corner
B) Reduce the height of the purchase pop up so it's not butting against the newsfeed icon.
C) MOVE the entire popup down so it's not so close to the top buttons. Heck, cover the buttons along the bottom.. it's not like anyone can use those until AFTER they close the annoying pop up.
I, personally, think the pop up every 2 or 3 screens is far, far, far too frequent, but I realize y'all ain't gonna change that.
