I have a new Leyzne Super GPS and a Leyzne speed and cadence sensor, also new. The GPS syncs with the phone perfectly. However, I can't get it to recognize the speed/cadence sensor. I have changed out the batteries to no avail. Are there any tricks to this or is my sensor defective?

There was a plastic cover on my battery when I got mine. It was a little hard to get off, but you tried new batteries... Did make sure you arepairing with Bluetooth option and with speed/cadence sensor? You might be able to try and pair the sensor with some phone app to test it out as well.

Make sure they are both the same system bluetooth or ant+.

I checked this. I'm fairly savvy with tech gear so at this point my sensor is bad or it's so obvious an issue I can't see it.

just got a macro gps and made the mistake of pairing the speed sensor first. Had to disconnect it and then pair with the cadence+speed sensor to get both. Something to check -- only have to pair the combo sensor; pairing it with one or the other will get in the way. To rephrase: if you paired the gps with your sensor as the speed or cadence by itself, it won't pair as the combo. And in the 'is it plugged in' category -- spin the pedals to wake up the sensor? --Does the sensor pair with strava or mapmyride etc?
