All the plans that are purchased on Metaplus will automatically renew based on your previous paid-plan. However, if you wish to change the plan from monthly to yearly or vice versa, you only need to cancel your up-coming payment and make the payment to the plan you want to purchase next. The new plan duration and features will be applied right away after the end of the billing cycle. However, if you downgrade your plan from Premium to Standard, you will lose access to the additional features provided by Premium plans
