Reason

Version number does not satisfy constraints (e.g. iOS version is too old)

Attestation statement creation time in the future

Signature counter in the assertion is too high. This could mean either an implementation error on the client, or a compromised client app.

Team ID and/or bundle ID and/or stage (development, production) mismatch

Happens if the challenge in the attestation record does not match the expected challenge

Generic case, which must not happen for an authentic app. could be borked assertion data (initial counter not zero, invalid attestation data, etc, KID mismatch). In general, it is hard to tell whether app developers made a mistake or something fishy is going on
