The update for Windows came out today. In *every* past submission to Microsoft, it had always been 3 - 6 hours. For some reason, this update took them 4 days. Argh. We tried very carefully to get all three versions of TM out at the same time (Android, iOS and Windows), but MS held up their release for whatever reason.
The new version is out and you will need to update to it in order to sync. Please check again.
