When it is not possible to see any content and features related to the coach, it is often a matter of one of these things:
Logged in with wrong user - if multiple users were created with a mistake
Log out and login with the correct email (the email were you received emails from coach). If you log in with another email you have not signed up with you will see the free Beefit version. To see the coach you have singed up with please use the same email you have received the emails to.
Beefit app is switch to 'free version' mode.
This mode is made for general tracking of workout. To switch back to the course with the coach, use the Change app button on the bottom of the PROFILE section - See image below
Note: This can only be an option if the Coach are offering our Beefit. Some coaches are having their own personal customized app, and here this change app button is not an option 😊
