"Deal damage to aircraft with AA launchers" is not tracked

I did this with 2 mates. myself and another had stingers while another was support dropping ammo.  I've noticed it only counts if the kill feed shows your launcher getting the kill or if you damage the aircraft someone else has to get the kill within a few seconds. Them crashing or bailing out wont count. Very annoying to get as the stinger would often blow up after being launched as well

Having the same issue. I have taken out a few helis and got the kills and still not going up at all. Restarted the game and nothing. Reinstall and nothing. (Xbox series x)

Yeah im having the same problem and was trying to figure out if I was using the wrong launcher. 

I have the same issue.

Same, spent all night last night and today trying to get any kind of credit on this, Ive been downing jets and Hellis with the SLM-93A and even tried shooting them down with the lock on launcher in the IFV.

I’m having the same issue. I’ve spent a whole night killing planes and hells, even tried the “AA tank” thing and still doesn’t track. Makes me not even want to play when things don’t work correctly.

Also getting no increase on the challenge......you think this would be addressed but its been like this since release.

Same here. Definitely not tracking. Used both AA launchers. 0 points. 

Been at it all day, only worked once on a heli, that’s it 

Same here. I've been trying this for days with 0 success. Still both counters are at 0 no matter how many planes I drop/damage.
