We recommend resetting Health access in Seven by following these steps:
1. Open Seven and go to Settings, then select 'Health' and turn the toggle off and on again.
2. Go to the Health and tap your profile icon > Apps > Seven > Turn all categories off and on again.
If the above steps don't help, please uninstall and re-install Seven, then connect to Health again. Before doing so, ensure that you're signed into a free profile in order to save your workout progress.
Please note: this won't sync past workouts but it should reset your connection to Health so that any future workouts will sync again.
