Cant reply to messages

I recently went back to an iPhone (6s) after having a Droid Turbo for 2 yrs. I didnt have any problems with my Pebble (other than the fact that the screen pixelates A LOT) while using my Droid but now with my iPhone, I cant reply to my messages. Theres not even an option on my watch when a text comes in. Im confused!
