Android Pay suddenly stopped working

[Erik Read]

Yesterday, for apparently no reason, Android Pay stopped working on my Pixel XL. Up until that point it had worked great. My device is not rooted and other than Developer mode enabled (weeks ago) it is stock from Google.
My error when I try to use it is:
Android Pay can't be used on this device
Google isn't able to confirm that your device or the software running on it is Android compatible. You may need to unroot your device.

Again...my device is not rooted.
One thing I noticed on the day this started happening was my device rebooted itself around 3 in the morning (it got really bright in the room so I looked to see what was happening).

The most recent thing I added to my phone was I connected a Samsung Gear S3 on the 17th. Android Pay has worked since then...just not today.

Any ideas?

Maybe install root checker just to verify you aren't? Tried clearing the app data?

Downloaded and verified not rooted. I have cleared the app data. Just waiting to use it again and see if that does it.

Who is your carrier?

By the way, do you have security (PIN or Pattern) setup on your phone? Android Pay will not work otherwise...

Thanks for the link. It looks like I am not the only one and that is 'good'.
My carrier is AT&T.
