I got a new 2017 surface pro and pen in January of this year. The pen worked great until February, when the right click button and pen tip stopped working. It also doesn't register when hovering or pressing down. The top button/eraser works, it is connected to bluetooth, and I'm pretty sure the pen tip is seated correctly. I've tried every troubleshooting guide and tool I could find, but nothing has worked so far. If anybody has any advice on how to proceed, it would be much appreciated, thank you!
