So far today I have joined 3 WZ turbo matches in progress and my req level is 9, but energy stays at 0. I left 2 of those games and I’m concerned if I keep getting games like that and quitting it might result in a ban 
joining a losing team in progress is bad enough, but having no req energy for the rest of that game is why I only stuck out 1/3 of em.
I experienced this same issue yesterday with Warzone Turbo.
I recall one game I joined in progress today not having the issue, three out of four did though, if my memory is correct. Helps to know I am not the only player who experienced the same bug.
