hi all,i have 2 questions on the xr please, as i am obtaining one this week.firstly, with reachability, if i enable it, does that mean by swiping up, then down from the bottom i don't have go right to the top of the screen to enable access to notifications? also, can i switch to apps with the equivalent of the lift and right gesture that sighted people use, to do the equivalent of the command tab alternative, or do i have to bring up the app switcher? thanks, Will B
