I have on mine, and yes it always prompts for a password anyways if I haven't used the App Store extremely recently (like within the past 24 hours).

I'd assume it's a straight-up bug on Apple's part, but they haven't fixed it for years and years, so at this point I think they're just being sadistic.

Because yes TouchID works everywhere else. This is App Store-specific. It's literally the only reason I keep a password manager app on my home screen, since it autofills everywhere else but not there so I have to always copy my Apple password manually from the password manager app.
