I purchased individual Premium for myself; then, a short while after, I created and joined a family organization. However, after a year passed, I was billed again for individual Premium despite having premium access through the family organization (which I was also billed for).
When a user joins a family organization, if they are also an individual Premium member, their individual billing should be suspended until they leave the organization.
It would be my preference as a user for it to automatically reactivate upon leaving the family org unless I specifically cancelled the individual subscription.
