Why do I have to pay again?

From what I understand, the app that is now called Crosswords Classic is being abandoned and I have to use this app now. But all the puzzles I try to download say I have to "upgrade" even though I already paid for what they now call Crosswords Classic. And all the puzzle "sources" I paid for are gone. The NYT puzzles are nowhere to be seen. The version description said they had fixed this, but they havent. Yeah, the "upgrade" is only $3.99, but why should I have to pay for what I already paid for? And, for what? Crosswords was never that great, but this looks worse so far.
