Help DDP Yoga Now App Compatibility with LG Nexus 5X Question

[la sal]

I downloaded the DDP Yoga Now App onto my LG Nexus 5X. I can perform the workouts with no issues. The problem is that when I try to bluetooth my Wahoo Fitness heart rate monitor chest strap, it can't pair or will crash the workout. This is disappointing because the app will log your average heart rate at the end of the workout. Any suggestions?

I was able to successfully pair it last night and it did not crash the app. It will not work with Smart Lock though.
