Surface Duo - Fingerprint reader not working

Same problem. Keep getting the message "sensor dirty", please clean?

I don't even have the fingerprint option in settings.  Also doesn't give me the option to enroll during set-up.

Any idea how to get the fingerprint reader working? Out the box the fingerprint sensor below the power button is not registering fingerprints. Perhaps the sensor is a dud. I tried restarting...powering down...powering up...nothing seems to work.

Here's what I did to get the fingerprint reader to work:

 - at first I tried using my left thumb assuming I could press the reader and open the Duo in the same motion. That didn't work.

 - so I switch to my right thumb for the reader and using my left hand to open the device.

 - by the way you do NOT need to perform the open/finger press at the same time. You can open the device and then press your finger.

 - When setting up your finger print press on the sensor, you should feel a small vibration, then remove your finger. Press again, vibration, remove and repeat. The object here is to move your finger a little each time you press. The Duo is attempting to build a copy of your print. Watch the display it will give you feed back as the press and repeat process takes place.

 - When I was given the "sensor dirty" error, I just rubbed the sensor with my finger a little and continued the press and repeat process until finished.

 - In settings, the fingerprint setup is in the Security section if you need to repeat the setup process.

My fingerprint reader stop working after about 6 days. I got it working after turning off Gestures in setting and going to 3 button setup.  It's been week now with no issures so far.

Mine has stopped working after two weeks.  Used the pin for a while.  It worked fine the first two weeks and has been inconsistent the past two days and now does not register at all. - Update: a power off brought it back. You have to use the pin after a power off, but after that it is now reading my fingerprint(s) very well.
