Installed GW18.1.1 and Mobility 18.1. POA not refreshing Mobility. The update to GMS 18.1.1 came out today and engineer updated. Did not help. They now are thinking something in network stopping the 4500 notifications from reaching GMS.

My device will get email synchs if I restart GMS... but not always ALL emails. Still looking into network issues with wireshark traces.
