I'm following the official Input System tutorials both on the Unity Youtube channel and Brackeys Youtube channel. Thing is, I'm using 2019.4.3f1 and the bloody things simply doesn't work. None of the callbacks are returning anything in their respective contexts. When downgrading to 2019.3, it does work. I haven't checked each and every version of Unity as I'm currently on a bit of a time clutch. Anyways, the documentaion on the unity3d website says that 2019.4 is supported and the pinner post here on the forum says it's still in the verification process. In the end, what is the minimum required version for the Input System to work?
