I’m a new surface pro 4 owner and love it. At first, everything was problem free but after a day or so my pen (flat edge pen that comes with SP4) would not open apps using the button. The button seems to have lost all functionality (it doesn’t make the led flash if held). The rest of the pen functionality is fine just I can’t open apps using the button. Microsoft have offered to replace the pen but I thought I’d need another one anyway so I bought a spare. Exactly the same problem! After a few days, the button just gives up!
Has anyone else encountered this or has any idea what may be wrong? Many thanks.
