lg g4 won't play Ron

I just bought a new lg g4 with 5.1 Android and can't log into Ron. When I try to open Ron Al I get is music and a black screen, every once in awhile I get music and a picture of the space station. I have tried uninstalling and reinstalling from both Google play and the spellbook website. Tried on both 4g and Wi-Fi. At a loss on what to try next,

Thanks for the report. We'll see if we can repeat it.
