The S pen (EJ-PT820BSEGWW) already have support in Onenote, but i would love if it was possible to also use the button on it for erasing.
I am able to do that on both my Surface Pro and Surface Book 2 with their original pens and a Wacom stylus and would love to have this function added for the S-Pen aswell since i use the Tab S3 at university for notes.

Yike! Just came and voted, then testing.. Amazing MS, come one more, more, more please :)
i stand corrected... this is now working with the latest onenote update for android
agreed... its unbelievable that I cannot use the button to erase, whereas you can in almost any other app
This is working now in feb 2019. Great!
