I was trying to login to iEra through PC Facebook, it seems that it won't work through Facebook anymore and it tells me that it will be soon removed due to the removal of Adobe Flash Player even though Graal has already been ported to WebGL. https://imgur.com/a/0nk2fOc

iEra still works through the official site (era.graalonline.com) but not on Facebook anymore, and I'm pretty sure this is miscommunication received from Facebook's end.
