Alerts from Ring 2 doorbell do not vibrate but alerts from Ring doorbell do.

I recently upgraded my front door to a Ring 2 from an original Ring. When motions occurred with the Ring, I get an alert tone, a banner and the phone vibrated (which is useful if you have the sound turned off). But since upgrading to the Ring 2, I only get the alert tone and the banner, no vibrations. I have the app installed on 2 IPhones and a Samsung tablet. All of them are consistent - no vibrations from the Ring 2. Is this normal?
