The Last Tiger challenge bug

Hi,

I know this has been posted before but I'll repost/ask again for visibility.
I have been trying to complete the challenges for this mission but it just won't happen no matter how many times I replay it, besides stating different things in game and the menu screen. While in the menu for the mission it says to reach the documents without alerting any enemies, but ingame shows that challenge is completed and that I need to reach the aa.

I've also seen some "fixes" that require you to get into your game's folder and whatnot but unfortunately I can't do that as I play on a cloud gaming platform (Geforce Now) and won't let you touch the game's files.

I'd appreciate some help with this please, really looking forward to unlocking that skin for the tiger. Already opened several cases and nothing helped.

Thanks
