Quick feedback. I find the return date selection to be non-intuitive. There is no clear indicator (on my screen) how to specify the return date. Tapping the screen and did the trick, but there was no indicator that said tapping the calendar again would choose the return date.
I completely agree now that you mention it. One of those things where you take it for granted but it isn't clear by default to everyone. On our website we have a highlight that indicates what your next click will do, and I think something to this effect will help on Android as well.
