Only the A and Start Buttons Work in One Nintendo JoyCon Mode on iPhone 13 Mini

Based on what you’re describing, I suspect that a single Joy-con doesn’t satisfy the iOS “extended controller profile” requirements. That’s what AnkiMobile can support. Preferences - AnkiMobile Manual

Update (my bad): Anki actually is compatible with all joy-con inputs; however, only when both R & L joy-cons are paired to the iPad / iPhone running Anki Mobile. Is obtaining complete joy-con input compatibility with AM (even when it is the only joy-con that is synced) still an iOS issue? I imagine most who interface with AM using a joy-con do so with only a single remote.
