SMS not vibrating when Phone on Vibrate mode topic

I'm having problems with my Moto 360 when it doesn't vibrate when the phone is set on Vibrate mode. If the phone is on ringer/silent, the Moto 360 will vibrate. Not sure if it's a setting I'm missing but I prefer to have my phone on vibrate and as insurance if I missed an SMS, the Moto 360 will vibrate on the wrist. BTW I'm using a Galaxy Note 4 (T-mobile)
