I”d just gotten comfortable using their iPhone app, and they went and improved it to where I can’t use it any more.
(My old iPhone tops out at iOS 7, and when I open the Ali app it insists I must upgrade to the new app requiring iOS 8. Can’t continue shopping using the old version.)

And no, there apparently is no way to let these netwits know they’ve screwed up and lost a passel of customers, no workable contact information option, just default options none of which apply.
