Ever since I upgraded to Windows 10, my surface pen is not working the way it should be. It writes, but the buttons do not work (making it really hard to erase). I spoke with someone at Microsoft and they said they were sending out an update last Tuesday. It has remained the same. I was wondering if anyone else experienced this issue and they were able to figure out a way to fix it. I am a student and it is really inconvenient when I usually use my surface for note taking.
