Xamarin Wrapper for Scanner SDK (Android & iOS) - BTLE opmode crashes Android app

We are using the Xamarin Wrapper for Scanner SDK and it is working as expected for iOS. However, on Android, the app crashes when the operation mode is set to OPMODE_BTLE, i.e.

ScannerSdk.ScannerManager.SetOperationMode(OpMode.OPMODE_BTLE);

The error is:

**Java.Lang.ClassCastException:** 'android.app.Application cannot be cast to com.zebra.scannercontrol.IDcsScannerEventsOnReLaunch'

The same thing happens if OPMODE_BTLE is selected in the sample XF scanner control app.

According to the docs, BTLE is supported.

I think it is a problem with the SDK, is there a workaround or fix planned?
