Used to work before latest update. When viewing each wallpaper, it takes you to an ad and won't let you back in. Hard to view them when this happens. And now when you click on them, and do a preview, the second screen is just black. App is now pointless and too much trouble to even use. I loved how your home screen could animate along with your lock screen but now it doesn't work. Had zedge for years, and now is Uninstalled. Hoping to find another app similar, that actually works. Disappointed.
