Members can remove any existing Tutor Sponsorships in their Preferences.
Tutor Sponsorship can be set up by a tutor to grant Premium status to a member (student). As long as the sponsorship is active, the member has access to all premium features regardless of their own subscription status.
Once you remove all existing tutor sponsorships, your Basic or Premium status will be determined by your underlying subscription status. If you do not have a current subscription, you will return to Basic. If you already have or start a subscription before removing your tutor sponsorship, you will have uninterrupted Premium status.
