We have an org with 15 networks. We're calling the following endpoint to pull some wireless event detail (client associations):
https://developer.cisco.com/meraki/api-v1/get-network-events/
However, one a few of our networks (but not all), the clientMac is null on the returned data, whereas on most networks, its populated as documented.
Before I raise with support, does anyone know of any reason why? It knows the client, as it does have the clientId - and if I look at this clientId in the dashboard it shows me the client mac!
Example response:

[snip]I checked over a 24 hour period and all 3,000+ records all return with a null clientMac.
What's more strange is that the same clientMac field is correctly returned for the "disassociation" event type, so it appears limited to "association" only.
Thanks,
James
