To restore your purchases, open Seven > Workout tab > Settings > Tap 'Seven' in the About section. Then, please tap the 'Restore Purchases' button once and wait for a few minutes for you purchases to be restored.
If your workouts are still locked after a few minutes, please make sure you are logged in to your Seven Profile (or create one if you don’t have one), then delete and re-install the app and try this approach again.
Please feel free to contact us if the issue persists.
