You can cancel a monthly subscription by looking up the yogi in your account from which you want to stop the subscription.
You click the subscription you want to stop to open this page, you will see a button to stop te recurring subscription. If you click here, Momoyoga will ask for confirmation. The subscription now expires on the next collection (renewal) date.
A yogi can not stop a recurring subscription themselves. The yogi is able to contact the studio to cancel a subscription by going to their schedule and look up the subscription. The yogi will see a button to cancel the subscription. This will lead to a message which is going to be sent to your studio. This way you can apply your own cancellation terms.
