I just bought a Acer Chromebook Spin 11. The description and Acer says the EMR stylus is supported, but it simply doesn't work.
I googled it, and supposedly there is a version of the Spin 11 with no stylus support. (What is the point of that, with far better Chromebooks that are cheaper!)
However, it is just impossible to know which one it is!
Acer told me on the phone that there must be something wrong with the one I got, but I doubt it...
There could be some software it needs or whatever, and besides this pen issue, the unit works perfectly.
So I hope anyone here could help me, instead of me returning it, and then most likely sending the same product, with the same issue back and forth until 2019.
