"Personal Membership"

I upgraded to the “Personal” membership a few days ago ($29 per month) and yesterday I deleted the app I was working on and now it seems I don’t have the membership any longer. Is that possible? I thought the membership stayed with my account. Do I have to pay $29 dollars again if I want my new app to have the benefits of Personal membership?

A plan is limited to an app, not your account as a whole.
