If you'd like to downgrade your account from MARE Plus+ to MARE Basic, you can do so from your account settings page.
1. Go to the billing page in your MARE account
2. Click on the cancel subscription button in the billing section
3. Confirm the cancellation of your subscription
That's it! Your subscription will not be renewed. You will retain access to MARE Plus+ until the next billing date listed in the billing section. On that date your subscription will be downgraded, and you will lose access to MARE Plus+ features.
