It's not possible to face 11.7 if your max BR is 9.3 in regular game modes.
Please double check your line-up, your game mode and BR displayed in tech tree (you can select auto, or arcade etc there, bottom right corner), if you are not in squad with friend who use higher BR than you (your squad BR display in hangar).
