Can't make it work on cellphone in portrait mode works fine in landscape and only an issue in Google not edge at all.      But makes every item flash then go white screen. Turning to landscape will give full function.

Hello! Same problem here. ಠ_ಠ

Turns out for me it was Samsung phone browser and cache issue.  Only happened on that device 

For me, it happens on random phones. For example, I have an iPhone and it doesn't work. The landscape is fine.
