If your subscription uses credentials, it is impeded from updating your password when a co-subscriber leaves your share. This will prevent unauthorized use of your account, maintaining the proper functioning of your subscription for your other co-subscribers and the security of your personal data.
For invitation subscriptions, ensure the departing co-subscriber is properly removed from your share group in the offered service. This will ensure that only authorized users have access to your share and will avoid any disputes.
Once the spot has been freed, don't forget to update the invite links that expire after a few days for your new co-subscribers.
