I'm on PS5, and yes I'm going to try and get some clips of this, just played another game where this time I was able to get to the fighter jet first. Can confirm that the missiles go through flares once locked on and there's literally nothing anyone can do. This is similar to the bug that was there previously with the IFV, except this doesn't require a friend to paint the target for you. Just lock on, fire and forget and the enemy jet went down 100% of the time.
If anyone else is experiencing this, what's the best way to get EA attention on this ASAP?
