I was afraid it was a dud and I'd have to send 50 lbs of trainer back to Wahoo.

Spent a few minutes on google and found someone who recommended turning off Zwift and unplugging the Ant Stick. Worked like a charm. SO, when you do spindowns, I just spin for 10 minutes on the Wahoo ap, THEN do the spindown, THEN plug in the Ant Stick and launch Zwift (assuming you're going to do Zwift or similar online trainer stuff)
