Splited app with obb : Target Image not working

I see that many people had this problem over time, even I did. I used to have a script that made the game work just fine, until now. I needed to upgrade Vuforia because of the black screen bug on IOS, I'm now using Vuforia 8.0.10 and it's working fine on IOS. BUT, it doesn't work anymore on android.

I obviously searched the answer but nobody seemed to have this problem on Vuforia 8.0.10 and of course, I tried the "https://developer.vuforia.com/forum/android/load-dataset-android-split-binary-obb" trick and others, but I can't make it work.

So if anyone had the same problem on Unity 2018.3.10f.1 & Vuforia 8.0.10 and managed to solve it, please help I'm desperate.
