Once you update the device names in your SecurlyHome app, they will be reflected immediately when you view activity reports on the same device. However, if you are viewing the activity reports on another device the device name change will not be displayed real-time. This is because the activity is displayed through the cache and refreshed at regular frequencies.
To view the device name changes you would need to refresh your reports page. Or you would need to wait for a maximum of one hour of inactivity for the changes to be reflected across all devices that house your SecurlyHome app.
