Fenix 3 HR / spin bike connection issue

I’m hoping someone can help me with this since Garmin support had no answers. Recently I got a new Fenix 3 HR as a replacement to my 910XT. At my gym, the spin bikes they have (Stages SC3) are ant+ enabled, and I have never had any issues connecting with the 910XT to get time, distance, speed, cadence, and power, which I assume is collected in the head unit on the bike and sent out together. Heck, I can even start and stop the 910XT (workout) from the bike console…

With the Fenix 3 HR, it is only able to find the power meter (and the power meters of several other nearby bikes), but nothing else. I specifically searched for speed / cadence sensors and the Fenix found nothing. Has anyone else been able to connect their Fenix 3 with a spin bike console (Stages or other) and not just an individual sensor component?

Thanks for your help!
