I've been unable to activate the Ready Check after queuing for a Veteran Dungeon through the Dungeon Finder, it only happens when I search for Veteran Dungeons, I don't have this problem with normal dungeons. The Ready Check doesn't pop up on my screen, and when I go to accept it through the Menu, nothing happens - the button doesn't work.
I'm just wondering if ESO knows this has been an issue for players the past couple days? My friend has been going through the same thing.
