I bought a Stylus EMR pen but it does not work with my Acer Spin 11. I have tried other stylus' and they do not work either. Is my chromebook not compatible with stylus'? I am extremely disappointed about this. I downloaded an app called INKed so that I can write with a finger or stylus. I use this chromebook for work and would have liked to have known that I couldn't use a stylus beforehand. Is there an update or extension I can add for this feature?
