Glyphs Viewer iOS

Glyphs Viewer is seemed broken in the latest version of Glyphs. I see only blanked iPhone screen even I have connected to my home computer and office computer. Any ways to fix it?
And have you got any plan to update it to 100% screen fit to iPhone? It’s a bit blurry now on iPhone 6S and 7.
I rely it heavily on designing Chinese characters for text use, thanks a lot if you could help fixing it! :slight_smile:
