If I turn on a light via Amazon Echo or via another app (like Belkin's Wemo app), the switch tile on the panel is not updating to the "on" position. When you press the tile, it doesn't turn the light on at that point (because it's already on) it just make the tile indicate that it's on. Press the tile again and it will turn off as expected. Seems like it just doesn't know that the other app turned it on.
Also, same thing happens when turning a switch off via another device or app.
