RYTM doesn't start when synced to Ableton!?

I’m trying to sync my RYTM using overbridge so that Ableton Live is master

For some reason RYTM does not start when I start Ableton Live, but my RYTM does stop when I stop Ableton, it also receives tempo messages correct.

My RYTM is set to receive both Clock and Transport and Live has been set to output and everything is updated.

I can make the RYTM behave correctly if I use the “USB-MIDI only”-option, but then I lose “Overbridge”

What is the secret trick that escapes me here?
