    We were using LTS 2019.4.21f1 and everything was fine with S-Pen inputs. Then we decided to update to LTS 2020.3.19f1 and now our playerbase is very vocal it being broken. Please fix this asap, I don't it's a viable solution to go backwards in Unity version.

    Fantastic, this would finally make the S-Pen usable. It would be great if this was also fixed in previous versions like LTS 2020.3.x
