Of course, you’ll always be able to re-activate a subscription that you previously unsubscribed to.
To do so, 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”.
Click on the latest subscription from the menu on the left, and then go to “Current Plan”. There, you’ll see the option “Reactivate my subscription”.
By clicking on it, a pop up will appear, asking you to confirm, and specifying the date of the following payment.
Select “reactivate” and you are done.
