I download the Glance app on my Lumia 521 months ago, but it's settings were no useable they were in light gray not selectable. I thought after the "Black" update it might work, which it doesn't. My wife didn't download the app when I did"same phone" now Windows store states that Glance is not available for download for the 521, but I have it. Does anyone else have it, & how do I get it to work?
