My report goes something like this for my Lumia 930.
No emails this morning, opened Outlook, manually initiated a refresh and mail came through. Verified that it is set to collect every 15 mins, so not sure why it didn't collect any mail overnight.
No notifications on lock-screen for any apps, though I did get a single number appear just once, but even then it didn't have the usual icon next to it, so I'm not sure what the notification was actually for. Can provide screenshot of this if anyone is interested.
Some live tiles don't seem to be working, missed calls, texts and Outlook tiles ok, but others such as Windows Central, Amazing Weather (see text below) not working.
