In order to unsubscribe, and stop paying for your subscription plan, you’ll first have to log into the platform, and access the page dedicated to your sub by clicking on the arrow near your name (top right corner of the page) and then “My subscription”.
From there, click on your current subscription from the menu on the left, and then on “Current plan”. There, you’ll see a short description of your current subscription plan.
In the bottom left corner of the screen you'll see the “Cancel subscription” option.
Click on it. You'll be able to choose whether you prefer to cancel immediately or to wait until the end of the billing period.
Select the preferred option and you are done.
