How many lessons do I have left?
Pack or subscription?
A lesson pack never renews by itself. The "Renew the package" button buys the same pack again.
A subscription (a course or a monthly plan) renews automatically, and you can turn the renewal off with one tap on the "Subscription" page.
How you know it worked
The numbers appear next to "Scheduled" and "Not Assigned", and tapping each one shows the lessons themselves.
