Long time iOS users, can you help me?

The apps you bought 10 years ago were 32-bit apps, they can still be downloaded to iOS versions up to iOS 10
Only the popular ones were ported to 64-bit later.

iOS 11 and above don't support 32-bit apps. That's why I kept my iPad Air 1 with iOS 10.3.3 for these older apps/games.

Yeah, I figured that much. It's just the fact that they do not show as purchased items that got me this surprised. They do not appear in my purchase list, like, at all. For example, the Moog synth has a new version in the App store, and I had that one that I used like crazy, but it simply does not show!
