If you've purchased a Proclaim On-Air license or Proclaim Pro Media and wish to change your subscription rate from monthly or annual, navigate to store.proclaimonline.com.
To change from a monthly to an annual subscription rate, cancel your current subscription (your remaining account time as well as all of your presentation data will be unaffected by canceling your subscription).
Once you've canceled your initial subscription, follow the steps in this article to purchase Proclaim through the app.
Remember: any remaining time that your previous subscription had will be added to your new purchase.
