Apple TV spin down issue

For some reason I can’t get the spin down to work through Apple TV. I get through the spin up to 23mph but it gets stuck and won’t go to next step. Anyone have any ideas?

Sorry. Should’ve mentioned…I use a kickr snap trainer.

Don’t use Zwift, except as a last resort. Do the spindown in the Wahoo app.


Thanks! Never done it through the wahoo app but it worked. Power seems more accurate now. Thanks again for the help!!
