Paul - Thank you for your thoughtful response. No longer disappointed, I did not understand from the App Store Update note that the functionality will not be affected for those who already made the purchase, at least until we upgrade or replace our devices. I appreciate you clearing that up, and I'm glad I purchased it before Apple screwed it up!

I'm really sorry Apple screwed you guys on this.

Feel free to delete my previous (uninformed) comment! I hadn't seen your other post, I saw only the App Store Update text and was routed directly to this page by a blog post.
