Hello everyone! I was waiting for a new update to post this. Unfortunately, I just updated to 71 and problem persists 
I have a 640 phone, I updated to several 10 preview versions from 8.1 without issues. Glance and motion data worked ok.
Since I was experienced some random freezes and app reboots, I decided to do a hard reset and start "fresh" on version 63. Unfortunately, after this motion data and glance screen stopped working. When I go to the settings screen it's just black and apps cannot find the sensorcore plug. I tried doing another hard reset, updating before and after joining the fast ring, but I could never make it work again. I even tried starting fresh, without restoring a backup config, but also no luck.
Do you have any advice on this? I would really hate to have to go back to 8.1 and update from there to get this working... thanks!
