Doesn’t work anymore – Macy's Review

My Macy’s app used to be one of the best I’ve used. And I used it often. When it prompted me to download the update I didn’t hesitate. Now when I open it, all I get is a black screen. I’ve tried to reload it several times with the same result. I couldn’t be more disappointed. Is there any way to revert back to the last version?
