Tacx Training app stops (pauses) when Garmin Edge 830 connects via ANT+

Hi everyone,

Since two weeks I have the Tacx Flux S. When I connect it with the Tacx Training app (4.35.4 (8879)) on my MacBook (MacOS Monterey) via Bluetooth it's all working. But when I turn on my Edge 830, connect it with ANT+ to the Tacx Flux S and start Free Ride, after some time (sometimes several seconds, sometimes a bit longer) the app pauses.

Second thing is that the Edge (no, not the guitar player of U2 but the thing on my bike Slight smile) also doesn't take the information from the app. So when I'm climbing 6% it still says 1% and descending with a lot of speed on the Tacx app (before it pauses) the speed on the Edge is slower.

Is this the way it should be or can anyone help me to use the Tacx app and the Edge 830 together? Thanks in advance!
