Yeah I agree @vermiliontower, i asked a different question, but quite relevant a couple weeks back here, Ive not dug through the source code nor am i an expert (so i dont know the differences between the platform dlls) but as a work around i just ended up referencing the monogame android dll in my shared netstandard library. PS - The keyboard input class will work as you expect (definitely on android although ive not yet tested it on iOS yet)
