Thank you Colludium, I hint your advise and used LiteTween, it works PERFECTLY.
Wow, that VectorX thingy is USELESS.
The Vector Y works though, but Vector X is Utterly USELESS with or without ignoring user input.
I will never touch Vector X for Platformer again.
I tried to work within the Platform's position placement feature because I don't want an external behavior that is not part of the Platform to affect positional movement to avoid glitches, seems like the internal Platform's vector X is a let down.
