Has the nerve to spam at you after you paid

Would get 4 stars but actually interrupts you with pop-ups trying to sell you crap or get you to rate it. Understandable for free apps, totally uncool for paid apps.

UPDATE: Seems it has issues with multiple displays also. In one case it wouldn’t function at all (could be related to VPN running). In most cases it just won’t change wallpaper for secondary display. I’m not usually hard on apps, but a wallpaper selector changer is something a child could program. The company should be able to get the basic functionality working.
