Unfortunately, no one here can tell you exactly, sometimes it's quick, sometimes it can take a while.
So wait and see when there is an update, you will hear about it 100%.
pubgm just released a update and changed their game version that is why the cheat is not injecting you need to wait paitenitly and wait for the update, I think at the time of writing this a update has already been released for the pubg cheat
usually when pubg gets an updated, it takes 2 or 3 days for the hack to be updated, meanwhile youguys can wait it out and right now its updated and working fine
