does still not admit it exists. Do I have to send that person a private message or something? Might actually get more answers then... or an infraction.
I may have found a possible workaround though, it is however not an acceptable one unless you want to blindly stare at your screen for 2 hours or more, while you cannot do anything else.
The workaround requires you to immediately reopen your group finder after queueing (at which point it may already have reset), this seems to lock your preferred role. HOWEVER, this also fills most of your screen making you unable to do missions or much else.
The official workaround given in this thrad is still utter non-sense. That button does still not exist and the problem remains, or at least returns within seconds or minutes most of the time.
