Hello @mjwheatley.
If you able, please check this issue.
Starting from (SDK 28) and higher versions of android sdk's, the FingerprintManager is deprecated in the biometric module.
Example: If you try to use FingerprintAuth.decrypt method on newer android versions you will get INIT_CIPHER_FAILED error because of FingerprintManager.CryptoObject is deprecated. You can reproduce it on Android SDK 28 and higher.
