When on my mobile, I can't use the XF highlight-and-add-to-quoted-text because the iOS copy/paste gets there first. Same thing happens on iPad, except the select tool goes right up to the top left corner selecting whatever is there, instead of the text I try to select.
I tried on a Lumia phone (Window) and it works, as on desktop.
Anybody else had this problem? Is there a solution to it?
