Marketplace App Update Manual Check Button and Last Check Time
Autoupdate is unreliable. A button to call for update check and cooldown to prevent spam. Show update last check time so we know it checked.

Many of my apps remain outdated because the autoupdate is unreliable. It's been weeks since one of the app update released and it isn't notifying me.
Let us know the last update check time or a manual update check button whether in Zune or WP's Marketplace.
