eBike support - cannot find sensor on epix 2

As there is eBike support added to epix 2 Beta firmware, I wanted to give a try.

I use my eBike (Shimano E7000 display) connected to Edge 830 without any issue for years, but I'm unable to pair it on epix 2 with FW 9.33, whatver I try to do, is there any workaround or fix? 

Thanks,
Peter
