iOS verifyFingerprintWithCustomFallback() method fallback error alert freezes the UI

[Jaishankarb]

we have used this plugin to login using the touch id and we are facing the following issue

when i call the function verifyFingerprintWithCustomFallback() on load for the success scenario it works but in iOS after continuous failed attempt the Biometry is locked so when you call this function on load it executes the error i am just triggering the alert in this error block.

now the alert window freezes the UI please see the attached Screen shot

this.fingerprintAuth.verifyFingerprintWithCustomFallback({ message: 'Sign in with the online ID ' + this.userName.substring(0, 3) + this.userName.substring(3).replace(/./g, '*'), // optional fallbackMessage: 'Password' // optional }).then( () => { this.navHome(); }, (error) => { dialogs.alert({ title: "Touch ID is locked out`",
message: ("please lock the device and unlock the device"),
okButtonText: "Ok"
});

    }
  });

}`

Add a little timeout before showing the alert. There can be one 1 alert at a time on ios.
