All actions applied by administrators are recorded in YTT Plugins -> Subscription -> Activities.
Search for a specific subscription using the dedicated search box and specifying the subscription name or ID.
Administrators can change subscription status when they want: go to the “Subscriptions” section of the settings panel of the plugin and select the related subscription. You can change the status with the action available in “Subscription Action”.
There is a difference between “Cancel Subscription” and “Cancel Subscription Now”. In the first case the subscription will be assigned the status “Cancelled” the day the renewal is due, while in the second case it will be immediately set to “cancelled”.
