Love the art effects but it's not working right now ? – Photo To Artwork Review

I've used this app a few months ago and had amazing results (glass effect on a nature picture = mind blowing) Lately, I tried again with new photos and NONE of the art effects work (you can still add stickers and such). I tried playing the entire ad, I've uninstalled and reinstalled the app, nothing works. Please help!
