Known issues​

  • Some devices (e.g. Google Pixel 6 with Android 13) blocks unlocking keystore via biometric authentication after 'wrong finger/face where presented too often'. This is a limitation of the device. In those cases app has to do a online login to IDP with his online credentials. MCSDK-1463
  • Digitanium Offline Function OTP: If MC triggers a RestartEvent internally i.e app will get a RestartResultEvent over the event bus (this can happen for example if there is some RuntimeErrorEvent), then the offline functions won't be supported and to mitigate the issue the app just needs to trigger a RestartEvent with the correct mc_config and offline functions will be available again.
