So my issue is since the maintenance yesterday I've not been able to log on I've tried restarting WiFi and phone but all that happens is a black frozen screen when I log on it never gets past the intro of mech arena with the black background then when that goes it's just a black screen I've tried waiting for ages but it does not work also I expect it to be fixed seen as I spend money on your game if it isn't then that money goes to wast
