Battle Pass: Season XII, “Armour Breaking Ambusher” Challenge Blitzkrieg says:
“Destroy a specified number of player vehicles while driving a tank at a speed of at least 30 km/h”

I did that many times (with M18 etc. in AB driving more than 50 km/h) and it didn’t count!?
Any experience? Maybe I didn’t understand the goal, maybe the target should be moving more than 30 km/h, not me?

Completed the Challenge. The catch was not to drive the vehicle automatic on MAX by double tapping E but manually by holding W.
