Was installing the new version and now you get a license emailed to you after ordering. I think the play store also gives one, but ordered mine here
https://premium.projectivylauncher.com/
Weird thing is I can't find the premium option on the base site projectivylauncher.com without Googling it. Maybe it's my adblocking DNS?
Did mine last night and finally premium on fire cube.
