Could you please check the close button ( the x sign ) for " Send message" on mobile. I tested on Android.
On landscape view is large enough, but in portrait view the x sign is so small and is very difficult to close the window.
I have to press many times to hit the middle of the x sign to close it.
I am talking about the window that opens from the top icon, not from the button link "Send private message" in profile.
This happens only when you want to cancel the message and not select any user. Basically when you write nothing and want to close it.
Maybe is just me, but please take a look at it.
Thank you
