CIQ apps on EDGE devices can't communicate via ANT PRIVATE channel

EDGE devices can't connect to private ANT channels, because they are not accepting ANT network key. 

deviceConfig = new Ant.DeviceConfig({
:networkKey64Bit => [0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX],
:deviceNumber => 0,
:deviceType => 1,
:transmissionType => 5,
:messagePeriod => 8198,
:radioFrequency => 57,
:searchTimeoutLowPriority => 10,
:searchThreshold => 0
});

GenericChannel.initialize(method(:onMessage), new Ant.ChannelAssignment(Ant.CHANNEL_TYPE_RX_ONLY, Ant.NETWORK_PRIVATE));
GenericChannel.setDeviceConfig(deviceConfig)


I deleted private key on purpose from the code above and sent it via mail as I don't think it should be communicate publicly. This ANT deviceConfig (with the right key) run fine on Garmin watch devices or even on simulator of EDGE devices (win 10 +eclipse 2021-06 + CIQ SDK 4.0.3), but not on actual EDGE devices (tested 1000, 830), where it throws this error.

Error: System Error
Details: 'No network key given, the ANT Private network requires a valid network key'
Time: 2021-03-14T13:21:10Z
Part-Number: 006-B3122-00
Firmware-Version: '7.10'
Language-Code: deu
ConnectIQ-Version: 3.2.5
Filename: Ant
Appname: Generic ANT
Stack:

Strangely on Edge 830 it force app to crash, while on Edge 1000, the app will remain to run, but do not open channel.

    Different ANT radio's require different network key sizes.  Most wearable radios (and most ANT usb sticks) require the 64 bit network key.  Most Edge's have a radio that requires the 128 bit network key.

    In general, I recommend providing BOTH the 64 bit (networkKey64Bit) and 128 bit (networkKey128Bit) network keys within the app when using private network keys.  The lower layers will automatically choose the 64 or 128 bit key as needed.
