Hi Kevin Z_0707,
Thank you for reaching Microsoft Community. We appreciate for sharing your concern to us.
The Surface Pen with no clip is compatible with Surface Go, Surface Go 2, and Surface Go 3. It supports pen and inking, Bluetooth, magnet attach, and tilt. So, it should work with your Surface Go 2.
Knowing that you have already tried changing pen tip and your pen still doesn't work. There is more likely a hardware problem on the pen itself.
- Is there a chance for you to test the pen on another Surface or test another pen on your Surface device? To really determine the problem.
For troubleshooting guide, see Troubleshoot your Surface Pen - Microsoft Support.
If pen also doesn't write on another Surface, then your pen needs a replacement.
Kind regards,
Lavenia
