[2021] RPG 3 Scorestreaks Camo not tracking at all

I know it's hard but it's definitely doable, I already have the Cigma Gold and every other camo on the RPG finished, including aerial streaks, except the 3 scorestreaks camo (science I believe). It's simply not tracking for me, it's 0/10 after countless hours. Tried following:

1) Dirty Bomb - destroyed at least 10 enemy vehicles in one game, including a UAV or two

2) The Cigma trick when you destroy first two streaks with it, then the third one with the RPG

3) straight up RPGd 2-3 UAVs (after so much trying I can hit them fairly often if no one else is using the Cigma) and 2-3 care packages (easy) in Nuketown 24/7 + some RCXDs and Sentries here and there

still 0/10

Anyone have any tips or fixes? I'm certain it's bugged for me, but can't find a single other post, all of the other ones are just saying how it's hard, which is not my problem
