Is "MIDI Guitar Rig IAP" now free?

Hi, I purchased “MIDI Guitar Rig IAP” for $9.99 in 2019 and now when I go to the store section it doesn’t show as “purchased” but it says the standalone version is “free” and only shows the IAP puchases for “MIDI output” and “plug-in and hosting”…, I also recently saw a friend who downloaded the IOS free app and when going to the store section it shows the same for him, so, what happened to the ones like me that paid for the “rig” version that is now free for everyone?
