Live Tile status
Live Tiles seem to work better than first thought so far.
Success rate in sending the tile has risen above 80%, which means that on average, if I'm sending the tile 24 times a day, you will get it 20 times. This is actually very good and can account for those times when the phone is out of coverage.
On the other hand there are still a few cases which have problems, they can mostly be divided in two parts:
1. people who have their push notification blocked on the phone
2. very frequent, long, "temporary disconnection" problems
n.1 means that -because of bug in the push notification service- your phone is 'locked' out of push notifications, for the most part. Apparently it can be solved only by the registry edit method or hard reset. So far I'd say it's a very small % of users that get this problem, but since I can't get any communication on the server from them, I'm not too sure. I'm in contact with 3 users who have this situation and will try if we can find alternative solutions.
n.2 is the network carrier problem. Some carriers are worse than others at mantain an open connection required for push. Tre Italia is one of these. I'm on Tre and can see this problem happen quite frequently. It usually goes away after a couple of hours, but sometimes it can last longer.
Either way, there isn't a lot I can do about it I think, but I'm glad it works for most people.
Please keep the good feedback coming in the marketplace to encourage development.
PS: by the way, my webservice is getting hit pretty badly with all the tile requests. If by chance one day you won't see updates anymore, it means it's blown up and I'm upgrading to a bigger one, hehe
