I got many reports from users that version 126.96.36.199 of Week View that was released a few days ago has major problems with updating the live tile. Sometimes the tile only show „partial“, sometimes it does not update at all.
Meanwhile I found the problem, fixed it and sent an update to the MS certification process on Sunday 06/07. Now I have to wait for MS to certify the update, which usually only takes a few hours. As soon as this is done, it will be available in the marketplace.
Sorry for the problem. 🙁
