Using StageNow to load WLAN certificates - Certificate Authority Error

Hi,

I'm using StageNow 3.0.1 to load a WPA2-Enterprise WLAN profile on a TC75x Nougat device.

Profile includes a Root certificate and during the profile creation I am required to Initialise the Keystore by entering a Keystore password.

Profile loads correctly on the device, but device has a persistent Android System alert "Certificate Authority installed by an unknown party" that comes up on every reboot.

Is this a known issue, and is there a way to stop this alert?

Thanks
