You must be a plan admin to cancel a Skills team plan. While you can’t cancel your plan prematurely, you can contact your account team to log your cancellation, which will go into effect at your next renewal date.
Note: You must cancel 30 days prior to your renewal date if your plan is on automatic renewal. Not sure if your plan is on auto-renew? If you see a Renewal Date date on your Account page (opens in new tab), that means your plan has auto-renew enabled.
