Black update - Lumia 925 Glance peek not working

hi! i figured since we're all in this thread because of glance, i'd put my problem forward. i had never used glance before the black update... it wasn't activated by default. so now that i have activated the glance app, it doesnt seem to be working correctly. i don't have issues with the sensors: it just seems to be stuck on "interval" with "lockscreen info" because changes to the glance settings are not reflected by the glance screen. at first, i had no problems changing the settings around... now it's stuck. night mode toggle and colors still work.

any ideas?
 
I got my 720 updated just yesterday. Since then my glance does not work. Setting for glance does not show anything. After soft reset the setting will show up but the glance only start for less then a second and died. And more, Nokia camera doesn't work properly. During amber days, both work flawlessly...maybe Nokia must work harder to correct the issues
 
I just registered to post this:
I think I've figured it out!
If the phone has entered powersaving mode, some features do not return to normal after being recharged. If you disable power saving, glance peek works again! Let me know your results :)
