This is happening on Unity 5.0.1:
I'm using Unity's Stored Procedure API to enable/disable notification devices by invoking calls to sp_ModifyNotificationDevice. The calls appear to go through just fine. I can verify via web/sa that the changes sent are in place. The problem is that notifications are never received on the device.
If I make the same exact change through web/sa then notifications go through. Also if I use web/sa and examine a notification device that was configured via the API, make a minor change (such as bump up the retry attempts) it will then start working.
Is there some other procedure call that needs to happen to make this work?
