Hostnames not Updating in Secure Endpoint Advantage/AMP for iPhones

[Thalen D]

We recently had to deploy 100+ iPhones in a hurry, changing to a new service provider before a major event. The Hostname of every new device is showing as "iPhone" in Secure Endpoint Advantage (AMP) even though each device is named for its user. This happened because the service provider, trying to be helpful, updated the iOS on every new device then wiped them before we worked with the users. Their update process let the phone register in AMP with the generic "iPhone" hostname, and now no matter what we do, the Hostname in AMP won't update. We tried removing the Cisco Security app from a device, deleting it from AMP and giving it some time, then adding it back in, but it comes back exactly the same, even with the same GUID. Is there a way to completely clear that cached device info/GUID from AMP before we add it back? Or another way to force it to update to the current Hostname?

Hello @Thalen D ,
did a short test in my environment. The hostname for the mobile device in my lab was changed within minutes. 
QQ, if you take a look at the computer properties, was is the last seen timestamp?
Greetings,

Out of around 800 mobile devices in our environment, a little over half of them have a generic hostname in our Secure Endpoint. We were approaching it as a deployment process issue prior to our recent big phone swap but it looks like there must be another cause. I have one test phone, not from this recent project, that shows an installed date of last year and last seen date of today. That device's hostname was updated on the device when the phone was deployed last year, but it never updated in SE. Of the batch of phones we deployed last week that show with a generic hostname, two thirds of them were last seen in the last 24 hours.
