Past Dec'19, I have been addressing the same issue such as, Unable to load, Black screen, VPN issues etc.. but sadly until date they dint consider an solution for it.

I have invested so much of Time & Money and unable to get an perma solution. Even in Puffin mobile, we are able to get only 1 hr free. The game also does not open in other websites.

I hope they will bring out some change or make an inbuilt VPN.
