Bug: Losing all sensor connections

Today, i became the new Garmin Edge1040,

so I configured it, properly. Connect all my sensors (HRMpro, Quarq Powermeter, Garmin Speedsensor2 ) and started to do a nice hilly ride.. 

but after  a few meters, he lost all connections. Sometimes during the entirely ride, he find them again, for a few seconds.

Parallel to the edge 1040 I used the new Forerunner to wrote the sensordata. It works without Problems. 

Sensor connections to the Forerunner 955 Ant+, to the Edge Bluetooth.

Firmware 12.11 it looks it‘s a early early beta. 

Very sad experience, to play the beta tester for such a device…
