Won’t let me use Watch app – Coach.me - Goals & Habits Review

I have coach.me on both my iPhone and my Apple Watch. The Apple Watch app won’t let me use it. It says Not Signed in. Please sign in on the iPhone app. I am signed in on the iPhone app, and I tried signing out and signing in again, but that did nothing. There is nothing on the iPhone app about connecting to the Watch, and nothing in the Watch app on my iPhone tells me anything. If the developers can tell me how to get the Watch app to work, I’ll reconsider my rating of the app.
