Can’t transfer my purchase to a newer iPad? – NaturalReader Text to Speech Review

I paid $9.99 for the pro version several years ago, and used it for 2 years during my masters program at school. It worked well enough that I decided to continue using it when I got a new iPad recently. However, the version showing up in my purchases is not the pro version I paid for. It only let me re-download a version with just a 15 minute sample. I don’t want to have to pay for it again for everyone of my devices. :(
