So I have to buy this again?

I bought the pro version of this app awhile back. And with the latest update, Im now being asked to buy or subscribe to more... And some of the features I have to buy (like changing strum patterns in chord camp), I had already bought with the pro version before. Looks like a great update, Im sure a lot of work went into it, but if current pro users are required to purchase all over again, just release it as a new product so it doesnt feel like were paying for something we already owned.
