Jan4 2017 App - no Bluetooth support

The Garmin smartphone app struggled with the Live features after my update to iOS 10.2 with erratic functionality. Live traffic being the most important feature. I have the nuvi 3597, purchased to use the BT live features, especially HD Traffic. The Jan 4 app update claims the 3597 is supported. The message I get when attempting to connect via BT on my iPhone 7+ is that the nuvi 3597 device is NOT supported by iOS. Garmin needs to fix its app. Right now, iOS 10.2 says the nuvi 3597 is incompatible with a Bluetooth connection.
