What happened?

I purchased it when it was a paid app (v.1.9) for $2.99 on 06/06/2014. Apparently, the app is now free and an in-app purchase is required to unlock the features I already paid for. I wouldve never updated had I known that I was going to be downgraded. This is extremely unfair, and I would appreciate a refund of my original $2.99, or a free upgrade to the “Full" version.
