iPhone names have changed to GUIDs

[spms1]

Hi,

iPhones used to show up in the client list with their name.  However, for the past couple of weeks or so, they have been showing up with GUIDs instead.  Is anyone else experiencing this?

I can't imagine how it would be related, but an MX84 was cold swapped into the place of an MX64, and the MX64 was repurposed at another building around the time this began.

I'm guessing your users have upgraded to newer iPhones or have updated their iOS to a version that supports mac randomisation.

I'm not sure that makes sense, as it's not the MAC address that is changing, rather the name.  The client name used to be "Person's iPhone" typically (whatever they named it upon setup), but is now a GUID instead.  The MAC addresses, I'm not sure about, as I haven't checked whether or not they are changing.
