Unable to enable Siri in macOS Sierra
I recently upgraded to macOS Sierra 10.12.2. I clicked on Siri and it asks to enable the same by opening the dialog box:
But clicking on the blue "Enable Siri" button doesn't do anything. No action, no matter how many times I clicked it.
Then I tried to enable it by going to: System Preferences > Siri > Enable Siri
This also opens the same dialog box and it goes in vain.
Kindly suggest any possible reason for the issue and solution.
Extra information: I am using the laptop in a VPN of my office.
Mac Pro, macOS Sierra (10.12.2)
