Help, app freezes

why can't I get my wallpapers to work also the app freezes up

Hi Jello, what is freezing? The editor? Are you running latest release? On which device are you on?

M9 running marshmallow, was trying to copy one of your Tutos off of YouTube but it only works in the app not on Nova and the app freezes up when I half through the Tutorial
