Your coach has turned on Macros tracking for you, but you don't see anything on your Today screen? And does the Coaching screen ask you to "message your trainer to learn more"?
Your coach is probably in the process of preparing your macros goals. Once they have your macros goals set up for you, you can be able to begin to log your nutrition data (or sync your meals over from MyfitnessPal).
So if you want to get started immediately, just check in with your coach to see when it will be ready.
Cheers and eat healthy!
