Messages Smart Reply Issue

I have had some pretty good success with it. I would tell you to try and send yourself a message saying "Where are you?", for me the responses are usually responses I would send out on a daily basis, for example...

a) On my way
b) In the Gym
c) At home

The initial responses were something along the lines of the following...

a) In the car
b) On my way

 

I have yet to be given the option of a smart reply. I've tried sending myself messages from the wifes phone with choices like "pizza or chips tonight", but I'm only presented with the preset replies. Replying to the same message on my iPhone gives me the option of "pizza" or "chips" from the QuickType bar.

Anybody else had problems with smart replies?

 

I unpaired/repaired the watch last week due to what seemed like excessive battery drain......and since then, smart replies have been showing up for me.
