My Alta has worked fine until the last couple of weeks. The text vibration notification has stopped vibrating. It still vibrates for calls and goal achievements, so I know the vibration works. However text vibration is one of the main reasons I got the Alta. Need to be able to glance to see who is texting without having to be rude to a client. I've tried removing device from the app and then reconnecting. I've tried removing the device from Bluetooth and then reconnecting. Please tell me there is something I'm just not doing right and that its not broken, I've only had it less than 6 months. Thanks, Tracy
